Gesture & focus testing — the hand-only checklist

Some Weavero surfaces cannot be tested programmatically: synthetic DOM events are untrusted (isTrusted: false) and XUL/native handlers ignore them, real drag sessions can’t be forged, and OS window focus is meaningless under a headless display. These run by hand. Companion pages: disable-testing, restart-testing, taskbar-overlay-testing (its S6/S7/S11 rows are part of this checklist on Windows).

Run the full checklist before a release; run the relevant section after touching drag/drop, window moves, or focus code.

Tab drags (main window)

• Reorder a tab within the strip — drop indicator tracks the cursor, tab lands at the indicated slot.
• Drag a tab down out of the strip → tears off into a standalone reader window under the cursor; the new window is focused; the source window reveals a loaded neighbor tab (not the library, unless nothing loaded remains); reading position preserved (no-reload swap).
• Drag a tab into another main window’s strip at a specific slot → lands at that slot; the dragged tab becomes the target’s active tab (Firefox rule); tab id preserved (check via List all tabs if in doubt).
• Multi-select (Ctrl+click) several tabs, drag the selection to another window → all move; the dragged tab (not the first) is active in the target.
• Drop a tab into the pinned region → auto-pins (icon mirror, leftmost cluster).
• Drag a pinned icon left or right of another pin → the pins reorder, both stay pinned (Firefox); the icon settles where it was dropped with no snap-back to its old place. Drag it past the pinned region → it unpins and lands at the slot; right after a group’s chip → it joins as the group’s first (pinned) tab.
• Press a pinned icon and release with a tiny wobble (a drag with no drop) → nothing changes: same place, still pinned.
• Press and HOLD a pinned icon → its tab is selected at once (mouse down, like a normal tab), before any release.
• Ctrl+click two pinned icons → both highlighted (the multi-selection outline), no tab switch; drag one of them out past the pins → the other folds away and the held one shows Firefox’s card stack behind it (one card for two tabs, two cards for more); on the drop both unpin and land together, the follower right behind the dragged one. Ctrl+click two normal tabs and drag them into the pinned region → same stack while dragging, both pinned side by side on the drop.
• Drag a pinned icon out past the pins → while dragged it grows into a full tab (icon + title); drag a normal tab into the pinned region → while dragged it shrinks to the icon. Neighbours make room for the previewed size, and the pointer stays on the dragged element. With the Firefox-style design on, NO blue anywhere in a drag: the previews keep the selected tab’s fill with no outline, a tab dragged in from a reader window shows a selected-fill pill with the violet focus outline, and a tab held over another tab (group creation) rings in the colour the new group will get. Design off: Weavero’s accent-blue outline and tint on all of them.
• ESC / drop back on the source strip mid-drag → nothing moves, no ghost window.

Reader-window drags

• Drag a reader-window strip tab into a main window’s tab bar → merges back as a tab, selected, same tab identity; the reader window closes if that was its last tab.
• Drag a main-window reader tab onto a reader window → mounts into its strip (move semantics — source tab closes).
• Ctrl+click two tabs and drag them to another window (main → reader window, reader window → main, reader window → reader window) → while dragging, the preview in the other window’s bar carries the same card stack as a same-window multi-drag (one card for two tabs, two for more) and, with the Firefox-style design on, the same 1px ring as the held tab, no outline; on the drop both land there, both still multi-selected, the dragged one active (Firefox: the selection is re-ranged over the moved tabs after a drop).
• Drag a group chip onto another window → the whole group travels; onto the desktop → group pops into its own window.
• After each move: scroll the document — position/zoom/selection survived; sidebar previews still render.

Cross-window item drag & drop

• Drag items from one window’s items list onto another window’s items list → items are added to the collection shown there (all of them, when multiple collections are selected).
• Cross-library variant → items copy once (linked copies reused); attached files follow when the target library allows file editing (group libraries with files disabled legitimately skip files).
• The source window’s collection selection and items list do not flicker or jump during the drop.

Focus rules (after any window/tab machinery change)

• Tear-off: the new window has OS focus. Known limitation (Windows, 2026-07-21): if the drag is released over another application’s window, that app keeps the foreground — Windows’ foreground lock forbids a background process stealing it back, so the plugin’s focus() is a no-op and the new reader window opens behind. Expected-fail; only drops on Zotero’s own surfaces or the desktop guarantee focus.
• Merge-back: the target window has focus and the merged tab is selected.
• Closing a window: focus falls to a sensible surviving window; the library tab is a fallback, not the default.
• Restoring a saved window/session: the restored window opens with its saved geometry (maximized windows reopen maximized) and does not steal focus from where you are typing (background restore).
• Reader tab: click into the item pane on the right, press Ctrl+F — the reader’s find bar opens (Zotero’s own binding only selects the hidden library search box there). With the cursor in a note in the context pane, Ctrl+F stays the note editor’s.

Reader pin bookmarks (after touching pin drag / _wvReaderShowPin)

The in-document pushpin for a position bookmark. Surface it: open a PDF, open Weavero’s reader Bookmarks panel, click a position-type bookmark row → the pin drops at that spot (it fades after a moment but stays while hovered). Then, at the mouse:

• Click the pin without moving → it stays put; the bookmark’s stored position is unchanged. (A press under the drag threshold is a click, not a drag — the lift is deferred until the pointer travels past it, so a click can’t nudge the tip.)
• Grab the head and drag slowly → the pin follows the hand from the grab point, not snapping its tip under the cursor (grab offset preserved).
• Drop on the page → the bookmark re-anchors to where the tip landed; the sidebar list re-sorts by location; the label auto-updates to “Page N” only if it wasn’t manually renamed.
• Drag off the page and drop → pin greys out / no-drop cursor while off-page, and on release the bookmark is unchanged (cancels back to its original spot).

Outline tab menu (after touching the Outline-tab wiring / page labels)

Page numbers (“p. N”) in Weavero’s Outline tab, issue #42. Open a PDF with an outline, switch the sidebar to Outline (Weavero takeover active), then:

• Right-click the Outline tab button → a menu in the annotations sort-menu format opens under it: heading ENTRIES TREE, then heading PAGE NUMBERS with rows ✓ Show (default) and Hide. No History section there. (Left-click and double-click keep their native meanings: switch tab, expand/collapse all.)
• Outline shortcuts (#51): Settings → Weavero → Extras → Reader outline → Keyboard shortcuts: all four boxes read None. Click Add selected text, press H → refused, “already used by the reader’s Hand tool”; press Ctrl+Z → refused (Undo); press T → “Saved.”, the box shows T. In a PDF, select text and press T → an entry is added from the selection; with nothing selected, T asks you to select text. Click into an annotation comment and type “t” → only the letter appears. The “+” menu and the page’s right-click menu show T next to Select text… / Add Selected Text to Outline. Press Remove → back to None, T does nothing in the reader.
• Outline undo keys: add an entry (any “+” flow) → Ctrl+Z with the outline focused → the entry disappears, the note strip says “Undone: Add Outline Entry”; Ctrl+Y (Windows; ⇧⌘Z on macOS, Ctrl+Shift+Z on Linux) brings it back. Select two entries, Del → Ctrl+Z → both are back at their places, selected. Right-click on the outline’s header strip → nothing (the history lives on the toolbar arrows since 2026-10-01); the source chip keeps its own menu. The history is per document and lasts this Zotero run — a plugin reload or update keeps it, a Zotero restart clears it.
• One history per tab, the most recent action first (2026-10-01): Ctrl+Z does the same thing from the page, the Outline tab and the Bookmarks tab. Add an entry from a text selection (focus stays in the page) → Ctrl+Z right away undoes that entry (“Undone: Add Outline Entry”); make a highlight after an entry → Ctrl+Z removes the highlight first (“Undone: Add Annotation” on the strip), the next Ctrl+Z the entry. With the outline focused, a highlight made after the entry is undone first too. Visible: collapse the sidebar, press Ctrl+Z after deleting an entry → the sidebar reopens on the Outline tab with the entry back and selected. Hidden panes count too (2026-10-02): delete an outline entry, switch to the Bookmarks tab, press Ctrl+Z → the sidebar switches to the Outline tab with the entry back; the History list shows outline, bookmark and annotation steps together whichever tab is showing.
• Bookmarks undo: in the Bookmarks tab add a bookmark (pin, page, selection) → Undo Add Bookmark (toolbar arrow, Ctrl+Z, Edit menu); rename → Undo Rename Bookmark; drag into a folder → Undo Move Bookmark; delete a folder with contents → Undo Delete Folder puts the folder and its children back where they were; select three rows, Del → one Undo Delete 3 Bookmarks. Drag a document bookmark into the Library section (move) → ONE step: undo it from either scope (Ctrl+Z in library scope or document scope) → the library copy goes, the document’s bookmark is back. Expanding and collapsing folders records nothing. Right-click on the pane’s header → no history menu (toolbar arrows only).
• Reach back and pick: after several steps, right-click a toolbar Undo / Redo arrow → HISTORY opens at the pointer; below Undo/Redo, UNDO HISTORY lists the 12 most recent steps, newest first, each with its age; a last row Show 12 older steps (“N more”) extends it by 12 per click, as often as needed, keeping ticks; a long list scrolls inside the menu. Each row (and the Undo / Redo rows) carries the glyph of the stack it belongs to — the Outline tab’s dot-and-line motif, the bookmark ribbon, Zotero’s annotation icon — and names it first in the tooltip (“Annotations — Undo this step and the 2 that go with it”). Click a row → that step and exactly the rows its hover bracket shows are undone, an unrelated newer step (e.g. a bookmark deletion between annotation steps) stays. Pick one or several: tick the box at the left of a row (or Ctrl+click the row) → the menu stays open, the row is ticked, and every later step that touched the same entries is ticked with it, dimmer (hover: “Needed by your pick”); a footer reads Undo N selected. Make steps on two different entries (add A, add B, rename A) → tick “add B” alone → Undo 1 selected → B is gone, A keeps its new name, Ctrl+Y brings B back; tick “add A” → “rename A” ticks with it. Groups are visible before ticking: hover any row → it and every row that must go with it get a blue left bracket and a tint (the hovered one darker); a row that cannot go alone says why in its tooltip. Untick a dimmer row → the pick that needed it is unticked too. Annotation steps group only by the annotations they changed (2026-10-02): make highlight A, highlight B, then change A’s colour → tick “add A” → “edit A” ticks with it, “add B” does not; tick “add B” alone → Undo 1 selected removes B and leaves A (with its colour). Click the footer → the ticked steps are undone newest first, the others stay (“Undone: N steps” on the strip). After two or more undos, a REDO HISTORY list (8 rows) follows, the next redo first, with the same boxes and its own Redo N selected footer; the tick box is a full-height zone from the row’s left edge to the glyph, so a click beside the box ticks rather than runs the row.
• Annotation undo shows where it happened (2026-10-02): with the Outline or Bookmarks tab showing (or the sidebar collapsed), delete a highlight on another page, scroll away, Ctrl+Z → the sidebar opens on Annotations, the highlight is back and selected, the page scrolls to it. Ctrl+Y → the highlight goes again and the page stays at its place. Same from the toolbar arrows and the History list.
• Toolbar arrows (PDF, EPUB, snapshot; main window and reader window): after the annotation tools (right of the colour picker), behind a divider, an Undo and a Redo arrow (Acrobat’s placement: tools, then the arrows); nothing overlaps the page count. The lower part of each curve is Weavero amber, like the funnel’s stem, so they don’t read as Zotero’s Back button. Greyed when there is nothing to do; hover → “Undo Add Outline Entry (Ctrl+Z) / Right-click: history”. Click → same as Ctrl+Z (strip note, reveal), the arrows swap their greyed state at once; make a highlight → Undo lights up without any other action. Right-click either arrow → the HISTORY menu at the pointer — also on a greyed arrow (then Undo / Redo greyed, no lists).
• Right-click in the page: no Undo / Redo items (removed 2026-10-01; the toolbar arrows carry them).
• Edit menu (menubar or the hamburger’s Edit ▸) shows the tab’s choice, like Ctrl+Z: after deleting an entry → Undo Delete Outline Entry — Ctrl+Z enabled and working, Redo greyed until something was undone; after a highlight → Undo Add Annotation. Never the library’s own actions (“Redo Trash 2 Items”) while a reader tab is selected. Click into a text field (the quick search, a note, an annotation comment) → Zotero’s own Undo, even right after a library action that Zotero could undo too. With focus in the outline or bookmarks, holding Ctrl+Z down undoes one step, not a burst. Library tab → Zotero’s own; there, Add Related / Remove Related done from Weavero’s relations popup and an annotation comment edited from a bookmark’s editor appear as Zotero’s own Undo Add Related / Undo Edit of “Comment” (Zotero 10+).
• ENTRIES TREE section: Expand All and Collapse All, their shortcuts dimmed at the right (+ / −); “Double-click, “ prefixes the one the tab’s double-click would do now (any entry collapsed → Expand All). Click one → the outline follows, the menu closes; right-click again → the “Double-click” hint has moved to the other row.
• Click “Hide” → the labels disappear at once, the menu closes. Right-click again → the tick is on Hide; “(default)” stays on Show.
• Switch to another document → its labels are still shown (the choice is per document). Back to the first → still hidden, also after closing and reopening the tab, and after a Zotero restart.
• Click “Show (default)” → labels return; weavero/outlines.json no longer carries a settings entry for the document (picking the default drops the record).
• Preferences → Reader outline → uncheck “Show page numbers” → every open reader’s outline drops the labels without a tab round-trip; the menu now reads Show / ✓ Hide (default); a document switched to Show from there still shows them.
• With another sidebar view selected (Annotations or Bookmarks), right-click the Outline tab → the same menu opens (it does not need the Outline view to be showing).
• TEXT SIZE section: Zotero Outline and Zotero Item Pane show their current size in a right-hand column (11 px / 13 px at View → Font Size → Reset), Fixed ▸ opens 8–24 px on hover. The three sizes line up vertically; “(default)” (dimmed) sits at the end of the Settings value’s line.
• Pick Fixed ▸ 20 px → the outline entries grow at once, only in this document; View → Font Size → Bigger leaves them at 20 px, while Zotero Outline / Zotero Item Pane documents grow with it. Pick the “(default)” line → back to Settings, and outlines.json no longer carries a textSize entry for the document.
• Right-click Outline → Bookmarks → Annotations → Annotations → Outline in a row → each right-click opens that tab’s menu, the second one on the same tab included (no toggle-close).

Outline entry right-click menu (after touching outline rows, menus or re-renders)

Collections-pane parity (2026-09-24). Any Weavero outline with a few entries; click one entry first so it has the blue cursor.

• Right-click another entry → dashed outline on it while the menu is open; the blue cursor and the selection do not move.
• Mark as Box / Sidebar (or Reset, Fix Spacing, Edit Region → Save) from that menu → after the outline redraws, the blue cursor is still on the entry you clicked first. (Not covered by a spec: the redraw needs a real reader.)
• Rename… from the menu → Enter → cursor stays; the renamed entry keeps the dashed outline until the next click or key. Reset to Original Name and Region does the same.
• Delete an entry you were not on → the selection and cursor stay.
• Ctrl+click two entries, right-click one of them → the menu says Delete 2 Entries and has no Rename…, Edit Region… or Reset.
• Open from the menu → the entry becomes the cursor and the only selection, and the view jumps to it.

Bookmarks tab menu (after touching the Bookmarks-tab wiring / page labels)

The Outline tab’s page-number menu, on the Bookmarks tab. Open a PDF with at least two bookmarks on different pages, Bookmarks tab active, then:

• Right-click the Bookmarks tab button → the same menu opens under it: heading PAGE NUMBERS, rows ✓ Show (default) and Hide. Left-click still switches to the tab; dragging an annotation onto the tab still bookmarks it.
• Click “Hide” → the “p. N” labels disappear from every row at once, the menu closes. The hover card still shows the page (it is the detail view).
• Switch to another document → its labels are still shown. Back to the first → still hidden, also after closing and reopening the tab and after a Zotero restart.
• Click “Show (default)” → labels return and weavero/outlines.json no longer carries a bmPageNumbers entry for the document.
• Preferences → Bookmarks → uncheck “Show page numbers next to document bookmarks” → every open reader’s bookmark list drops the labels without a tab round-trip; the menu now reads Show / ✓ Hide (default); the Outline tab’s own labels are unaffected.

Annotations-list funnel (after touching the sidebar funnel / list filter)

Issue #43: hide annotation types from the reader’s sidebar list while they stay on the page. Open a PDF with at least one highlight and one ink stroke, Annotations tab active.

• A funnel sits right of the sidebar search magnifier (same look as the Bookmarks tab’s funnel). It is absent on the Bookmarks, Outline and Thumbnails tabs.
• Hover the funnel -> background tint only, exactly like the funnel in the reader’s own toolbar; the funnel icon must NOT change colour (synthetic events cannot drive :hover, so this one is hand-only).
• Click the magnifier -> the search input opens on its own line under the toolbar, full width, the funnel stays where it was; typing filters the list; Escape closes the line; whatever sat under the toolbar (sort bar or list) moved down and moves back.
• Open the funnel -> the popup is titled “Filter Annotations Pane”, opens BESIDE the sidebar (over the reader, top-aligned with the button, never covering the pane), and carries every row the funnel above the reader has: colours, types + Has Comment, Has Tag / Related / Link, tags, people (group libraries), Added and Modified date ranges, the “Alt+Click to Exclude” hint. It must NOT carry “Hide Annotations in the Reader” – that one is document scope.
• Alt+click Ink -> ink rows leave the pane, the strokes stay drawn on the page. Click a colour -> only that colour is listed, the page still shows everything. Click an active chip again -> neutral. Clear and the red x reset every row.
• The funnel gets the accent dot while anything is set, and the footer says “N of M hidden from the pane” plus “this document only” with “Use as default” / “Back to default” (or “default for all documents”).
• Select All in the sidebar (Ctrl/Cmd+A) -> no ink annotation is selected; arrow keys skip them.
• Click an ink stroke on the page -> it selects on the page; the list shows no row for it (expected: hidden means hidden).
• Reopen the tab / restart -> ink still hidden in this document; a different document lists ink.
• Use as default -> footer reads “Default for all documents”; Preferences -> Reader annotations pane shows Ink unchecked; another document now hides ink too. Back to default on a document that departs restores the default set there.
• Toolbar funnel excludes Highlights while the list hides Ink -> the list shows neither; clearing the toolbar funnel brings highlights back and ink stays hidden (the list never re-shows what the toolbar funnel removed).
• In-view popup for a hidden ink annotation (sidebar closed, click the stroke) still renders.
• Use as Default -> the CHIPS DO NOT MOVE (an included chip stays included; it must never turn into the equivalent set of exclusions), the footer flips to “Default for All Documents”, Use as Default gives way to Clear Default, the funnel gets a GREEN LINE underneath (a default other than “show everything” exists; the chips the default sets carry the same line, in every document), the blue dot goes (the dot means this document DEPARTS from the default, not that a filter is active), and Preferences -> Reader annotations pane shows the matching types unchecked. Another document follows. Add a chip on top -> dot AND line. While a default exists the header reads Clear All / Reset (tooltip “Back to Default”, just before the red ×, which is then “Back to Default and Close”); without one it is the plain Clear / “Clear and Close” pair and no Reset. Reset restores a departing document; Clear Default returns every document to showing everything. Alt+click Use as Default ADDS this document’s chips to the existing default instead of replacing it.
• Zotero’s own selector (colours / tags at the foot of the pane) is SHOWN with a handle by default while Filters are enabled: a centred pill in its top padding, the colours and tags under it exactly where Zotero puts them. Click the pill -> folded to a thin strip with the pill, nothing else; click again -> unfolded. Every open document follows, and a restart keeps the state (up to 0.22.1 the default hid the selector outright). Select a colour, fold -> the pill turns blue and its tooltip says a selection is active; the page stays filtered. Unfold, deselect, fold -> grey again. Drop an annotation card on a colour while unfolded -> recoloured (Zotero’s own drop). Settings -> Reader annotations pane -> untick “Handle on Zotero’s colour and tag selector” -> no handle, the selector always shown, as in Zotero (the box ENABLES the handle, it is not the toggle; MJT 2026-10-14); tick again -> the handle, in the state it was left in. Filters master off -> the same native look.
• Tag Selector handle (library tab): a pill centred on the Tag Selector’s top edge. Click -> the selector folds shut (only the divider line stays); click the pill again -> back at its previous height, same tags highlighted. With a tag selected, fold -> the list stays filtered and the pill turns blue (tooltip names the tag). View -> Layout -> Tag Selector shows the matching check mark in both states, and hiding it from the menu then clicking the pill brings the selector back WITH the filtering tag highlighted (Zotero’s own re-show leaves it unhighlighted). Drag the edge beside the pill -> still resizes, and the pill stays where it was (12 px under the divider, never 0 px tall: the splitter’s drag used to write a height on it). Restart with it folded -> still folded, and the pill unfolds it. Settings -> Extras -> Collections pane -> untick “Handle on the Tag Selector” -> plain splitter.
• Settings -> uncheck “Filter the annotations pane” -> the funnel disappears, the pane shows every annotation again, Zotero’s selector comes back. Re-checking restores the funnel and the document’s own filter.

View → Layout follows the tab (after touching the menubar wiring)

zotero#2814: Zotero’s Layout items toggle the library’s panes whatever the tab. Weavero shows the reader’s panes there instead.

• Library tab → View → Layout: Zotero’s Collections Pane / Item Pane / Tag Selector, nothing else, check marks as Zotero sets them.
• Reader tab → View → Layout: Sidebar, Context Pane, Colour and Tag Selector; Zotero’s three are gone. Check marks match what is on screen: toggle the sidebar with its toolbar button, reopen the menu -> the mark followed; same for the context pane (sidenav toggle). Click each item -> the real thing toggles: the sidebar; the context pane; the selector goes ENTIRELY, pill included, in EVERY open reader (one state, kept across restarts) – the pill only folds it, this hides it, as the library’s Tag Selector item does. Unticked and the pill’s fold state are independent: hide, show -> folded or not as it was.
• Note tab (a note opened as a tab) → View → Layout: Context Pane, toggling the context pane – and, with Better Notes installed, Outline Pane above it, toggling Better Notes’ outline (its mark follows the outline’s own close button and the editor toolbar’s reopen button).
• Back to the library tab: Zotero’s three items are there again (nothing stays hidden after a reader-tab open).
• Separate reader window → View: a Layout submenu at the end (same label as the main window’s), with Sidebar, Context Pane (only while Tabs & Windows → “item pane in separate reader windows” is on; it toggles THAT pane) and Colour and Tag Selector. With “Hide title bar” on, the same through the hamburger’s View cascade.
• Keyboard: Alt+V, L (Layout), then the first letter of an item – the reader’s items answer to letter navigation like Zotero’s.
• Settings → Extras → untick “View → Layout follows the tab” → reader tab shows Zotero’s three again; the reader window’s Layout submenu is gone; tick → back.

Annotation card dates (after touching the sort menu or the card rendering)

Issue #49: the reader’s annotation cards can show when an annotation was added / modified. Open a PDF with a few annotations made on different days, Annotations tab active, sort menu (the arrows icon) in view.

• Sort by Position, tick “Date Added” in the sort menu -> every card gains one “Added: " line under its text; untick -> the line goes.
• Tick both “Date Added” and “Date Modified” -> two lines, Added first.
• Sort by Date Added (or Modified) -> the cards reorder by that date and BOTH lines show, the sorted one first, whatever the ticks say.
• Hover a date line -> the tooltip carries both full dates (“Date Added: …” / “Date Modified: …”); the card header’s own tooltip carries them too and keeps Zotero’s “(user)” part.
• The sort menu rows read “(default)” on the entries Settings marks as the default; changing the default in Settings -> Reader annotations pane updates the rows and the open documents without a restart.
• Reopen the tab / restart -> the ticks and the sort survive.

Sidebar link icons while scrolling (after touching the sidebar comment previews)

A sidebar card whose 3-line comment hides part of a link carries the link icon next to its ⋯ button. Open a PDF with more annotations than fit (the Weavero test fixtures PDF has short and long URL comments), Annotations tab active, nothing selected.

• Scroll the list down slowly -> each card comes into view with its final icons: the link icon only on cards whose comment is cut off at three lines, never on a one-line comment. Nothing changes after a pause or a click (2026-10-23: off-screen cards got the icon by mistake and lost it only on the next click).
• A card with a Related button and a cut-off link -> both icons, the link icon left of the Related chain.

Session list sort (after touching the Sessions section of the List-all-tabs panel)

Open the List-all-tabs dropdown; the Sessions header carries the annotations-pane sort control at its right: a dropdown chip naming the kind (Created ▾) and an arrow chip (↑ / ↓).

• Click the chip → a menu with Created, Name, Last used; the current kind ticked; “(default)” dimmed at the right of Created.
• Pick Name → the saved sessions re-order in place, the panel stays open, the chip reads Name ▾; the current session stays the header at the top and Last workspace (auto) stays last.
• Hover the arrow → the tooltip says which way the list runs (“A to Z”, “Oldest first”, “Most recent first”…) and “(click to reverse)”. Click it → the list flips, the arrow turns. Pick another kind → its natural direction again (Name ↑; Created and Last used ↓, newest / most recent first).
• Sort by Created or Last used → each session shows that date under its name (time only when it is today’s); Name shows no date line. Hover a row → the tooltip carries the action, then “Created: …” and “Last used: …” in full, in every mode.
• Reopen the panel after a restart → the chosen kind and direction are still in force.
• Clicking a session row still switches to it (the two chips are the only new click targets).

Items-list width (after touching the table CSS or registering columns)

The items-list header must not size the centre pane (2026-09-11: with three Weavero columns the header’s intrinsic width exceeded the pane’s share, the side panes were squeezed, column drags moved the centre pane, and titles on the ellipsis boundary blinked). Show a dozen columns including Weavero’s Annotations / Tags / Related, then:

• Narrow the window until the items pane is at roughly its minimum → the collections pane and item pane keep their splitter widths; columns shrink inside the items pane instead.
• Drag a column separator (e.g. Creator | Year) → only that pair of columns changes; the centre pane and the other columns stay put.
• Drag the separator before / between Weavero’s count columns (Notes | Annotations, Tags | Related, …) → they resize like Zotero’s Notes column (2026-10-23: they were fixed-width, two digits fit and nothing moved); a 3-digit count shows in full once widened; the width survives a restart.
• Right-click the header → Tags ▸ (two main windows open) → the Tags line carries the column’s check and opens a submenu: Show Column hides / shows the column; Automatic-Tag Count turns the second number on or off in THIS window only (the other window keeps its own); flipping the Settings switch leaves a window that chose alone; after a restart each window keeps its choice (2026-10-26).
• Watch truncated titles for a few seconds at that width → no blinking between “Tes…” and “Test12”-style renderings.
• Narrow the window to ~1000 px with a dozen columns shown → at its minimum the FIRST column (whichever it is: Title, or Creator once moved first) still shows about as much text as the other squeezed columns do (its floor is Zotero’s 30 px plus the 36 px of twisty slot and type icon its text sits behind); below 930 px Zotero stacks the item pane by itself. Then drag the first separator hard to the left → the first column stops at 66 px and no other column moves.
• Move another column first (drag its header to the left edge, or right-click the header → Move Column) → the floor follows: the new first column stops at 66 px, the previous one shrinks to 30 px like any other. Move it back → same, reversed.

Side panes: drag, collapse, reopen (after touching splitters or the reader-window item pane)

Synthetic drags do not move Gecko splitters, so these are hands-only. Setting: Extras → Collections pane → Resizing a side pane stops at its minimum width.

• Setting on: drag each pane edge hard past its minimum → it stops: collections pane 200 px, item pane 357 px, the context pane of a reader tab 357 px, the item pane of a reader window 357 px.
• Setting off: the same drags snap each pane shut, as in Zotero. In a reader window the pane and its icon column go and the reader toolbar shows the toggle at its right end.
• Reader window, either setting: collapse with the icon column’s top button → pane and column gone, toolbar toggle appears with no frame of the funnel at the toolbar’s end; the toolbar toggle reopens the pane; the MAIN window’s context pane never changes.
• Reader window open across a plugin update or reload → its item pane behaves as the new build (it is rebuilt in place, collapsed state kept).
• Collections-pane button on, pane collapsed → the band at the left edge is 1 px; button off → Zotero’s 8/10 px band is back.

Hidden collections (after touching the collections menu or tree filter)

Real right-click menus; the spec builds them without opening.

• Right-click a collection → Hide, with Zotero’s crossed-eye icon as on Unfiled Items (at the end of the menu); it and its sub-collections vanish, a blue dot appears at the end of the My Library line (hover: “In this window: 1 hidden …”); select My Library → the dot turns white on the blue selection (the row’s text colour, so it stays visible on the grey unfocused one too).
• Ctrl+click two collections and a saved search, right-click inside the selection → Hide 3 Collections and Saved Searches.
• Right-click My Library → Show Hidden Collections ▸ sits in Zotero’s Show group (its own Show Unfiled Items… fold into it) → Manage Hidden…, Show All (n), then each by path, with its row’s icon (collection, saved search, Unfiled…, group, My Library), in the pane’s order (Recently Read, collections, saved searches, My Publications, Duplicate, Unfiled, Retracted — the (all windows) entries at their own places), the Recently Read clock purple as in the tree; pick one → it is back, the dot goes when none are left. With nothing hidden there is no submenu: a plain Manage Hidden… item sits in that same place.
• Right-click a collection and a saved search: Hide sits right above Zotero’s Delete Collection… / Delete Saved Search… (on a special collection, in place of Zotero’s own Hide). On My Library or a group library: right above Show Hidden Collections ▸ (or above Manage Hidden… with nothing hidden), both in Zotero’s Show group.
• Manage Hidden… → its own window, with the usual minimize / maximize / close buttons and resizable: two of Zotero’s own collection trees, Shown on the left and Hidden on the right, drawn exactly as the collections pane (icons and their colours, fonts, row height, twisties, selection colours, Weavero’s indent guides when they are on), without the virtual rows (Unfiled, Duplicates, My Publications, Bin…). It opens about 760×560, centred on its main window, whatever size the Plugins Manager last had. The left tree opens and closes as the pane shows it right now; opening or closing branches in the manager leaves the pane’s remembered expansion alone. What you open or close in the manager is remembered for its main window: close a hidden collection on the right, close the manager, open it again → still closed (a shown row starts as the pane shows it at that moment).
• Rows that cannot move are grey italics with a tooltip saying why: My Library and the Group Libraries heading on the left; on the right the library rows and parents that only give a hidden entry its place. Selecting only such rows leaves Hide → / ← Show off. What a hidden collection, library or section hides with it CAN be selected (2026-10-21): its tooltip says what ← Show brings back (“Hidden with its parent collection: Show brings the parent back”), and Show does that – drop a collection onto a hidden collection’s row (it becomes its child, Zotero’s move), select it on the right, ← Show → the parent and it are back in the pane.
• One selection (2026-10-21): select on the left → Hide → on; then select on the right → the left’s selection is gone, Hide → off, ← Show on; and back. Only the pane you work in holds a selection.
• Select on the left (Ctrl+click, Shift+click, every collections-tree key: arrows, Left/Right, +/-, Home/End, type-to-find) → Hide →, Enter or double-click: the entries leave the collections pane at once, a parent takes its sub-collections, they appear on the right (brought into view), and the selection moves to the next row; the same back with ← Show. Delete and F2 do nothing here. ← Show All (under the pair) brings back everything on the right at once — this window’s set and the (all windows) rows — and greys out when nothing is left.
• Right-click a row (or inside a multi-selection; the Menu key / Shift+F10 too) → Zotero’s collection menu on the manager’s own rows: New Subcollection… (Zotero’s dialog), Rename (inline, as F2), Move To ▸ (this library’s root and collections, never into itself or a child), Copy To ▸ (every library), Hide → on the left (Hide 3 → for three) / ← Show on the right, Delete Collection… / Delete Collection and Items… (Zotero’s confirmation; the Delete key, Shift+Delete for the items), Export…. A saved search gets Hide/Show and Delete Search…; a library, section or special row Hide/Show alone; a read-only group’s editing items are greyed. On a row outside the selection the row becomes the selection first; on a grey row with nothing movable selected the item is disabled. Expansion follows a move: open a collection on the left, hide it → it arrives open on the right (its sub-collections visible); close it there, show it → it comes back closed on the left. The rows around it keep their state.
• The Filter Collections box (Zotero’s own, Ctrl+F) filters both trees as the pane’s filter does: matches with their parents as grey context rows, branches opened, the earlier layout back when cleared (Escape clears it; Escape again closes the window). A selected row that stops matching never arms a button.
• Escape, Ctrl+W or the close box end the manager; a second Manage Hidden… focuses the open window; closing the main window closes it. Resize it, close it, then open the Plugins Manager: it keeps its own size. The Group Libraries line’s menu has the same item.
• Right-click a group library → Hide; a dot on the Group Libraries line only (My Library’s dot and menu stay about its own collections). Right-click the Group Libraries line → Show Hidden Group Libraries ▸ (with nothing hidden there, a plain Manage Hidden…). Hide every group → the line goes; only then does My Library’s dot count them and its Show menu list them under “Group Libraries”, with a label that says what it holds: Show Hidden Collections and Libraries ▸ with both kinds hidden, Show Hidden Group Libraries ▸ with only groups hidden. Show one group → the line is back and My Library’s menu drops them again.
• Whole sections (2026-10-20): right-click the Group Libraries heading → Hide is its first item (Zotero’s crossed-eye icon; absent while My Library is hidden) → the heading and every group go; join or create a group → it stays hidden. Right-click the Feeds row → Hide → the row and every feed go. My Library’s dot counts “the Group Libraries section, the Feeds section”; its Show Hidden Libraries ▸ lists Group Libraries and Feeds with the rows’ own icons; each entry (or Show All) brings its section back. In the manager the heading and the Feeds row can be selected and Hide → hides their section; on the right ← Show brings it back; the groups / feeds under them can be selected too and ← Show on one brings the whole section back (“Hidden with the Group Libraries section: Show brings the section back”). With the Group Libraries section hidden, My Library cannot be hidden (the last library shown).
• Single feeds (2026-10-21): right-click a feed → Hide (right above Unsubscribe from Feed…) → its row goes, the Feeds row stays and gets the blue dot (“1 hidden feed”); right-click the Feeds row → Show Hidden Feeds ▸ (right under its own Hide) lists the feed with its icon, Show All (n) and Manage Hidden…; one click brings it back. In the manager a feed can be selected on either side and Hide → / ← Show move it; on the right it sits under the Feeds row, which stays grey (it is not hidden itself). With the whole Feeds section hidden too, the feeds hidden one by one stay hidden when the section comes back.
• No arrow over nothing (2026-10-21): hide the only sub-collection of a collection → the parent’s expand arrow goes (collections pane and the manager’s Shown side alike; on the Hidden side the parent is the context row holding it and keeps its arrow); show the child → the arrow is back.
• Drag and drop in the manager: drag a collection onto another collection’s row (either pane) → it becomes its subcollection (Zotero’s own move, its rules: never into itself or a child); onto a library row → back to that library’s root; onto another library’s row → a copy there. The pane the row is in decides the rest (2026-10-21): a drop on a row of the Hidden pane — a grey context row included — also hides the collection in this window, a drop on a row of the Shown pane shows it; the target row opens and the moved collection is selected there, as the collections pane does. Hovering a closed collection for a second while dragging opens it (Zotero’s own). Drag a collection, a saved search, a library row, the Group Libraries heading or the Feeds row onto the free area or the caption of the Hidden pane (the pane’s border and caption light up) → hidden; the same onto the Shown pane → shown. A collection dragged from the collections pane of the main window onto the right pane’s free area is hidden too.
• Pinned parents in the manager (2026-10-21): with Keep parent collections pinned at the top while scrolling on (Preferences → Weavero → Extras → Collections pane), expand a deep branch and scroll either tree of the manager → the parents of the rows at the top stay pinned above them, outermost first, as in the collections pane (same level cap). Click a pinned row → its own row comes back under the remaining pinned rows and is selected; its arrow collapses it. Right-click a pinned row → the manager’s own menu for it, the row selected as from its own row (a grey context row pinned is grey and cannot be selected). A drag over the pinned rows lights no zone and drops nothing. Switch the setting off → the pinned rows go from the collections pane and the open manager alike; on again → back.
• Special collections (2026-10-19): right-click Unfiled Items (or Duplicate Items, My Publications, Retracted Items, Recently Read) → Hide is Weavero’s: this window only, the row goes, and Zotero’s own Hide (its setting, every window) is not offered. Right-click My Library → Zotero’s separate Show Unfiled Items… entries are gone; Show Hidden Collections ▸ lists Unfiled Items among the collections. Hide Duplicate Items the Zotero way (switch Weavero’s Extras off, right-click → Hide, Extras on again): the dot stays OFF — the special collections never light it, hidden here or by Zotero’s setting (hide a real collection too: the dot counts that one alone, its tooltip names Zotero’s as “hidden in every window”) — the submenu lists it as Duplicate Items (all windows), and that entry (or Show All) brings it back in every window. The Bin never appears in any of this.
• Manager, special collections: Unfiled Items, Duplicate Items, My Publications and Retracted Items (Recently Read on Zotero 11) sit under their library on the left; Hide → moves one to the right like a collection. My Library can be hidden like a group library — while another library is shown: with it and a group shown, select it → Hide → it moves to the right, the pane shows the group alone, and the Group Libraries line’s dot and menu list My Library; ← Show brings it back. The last library shown, the Group Libraries heading and the grey context rows cannot be selected (a click leaves them unselected, the arrow keys skip them; the tooltip says why). Ctrl+A takes the rows of the selection’s level, as the collections pane does, but with the saved searches and the special collections of that level included (from a collection, a saved search or Unfiled Items alike: every movable row under the same parent; from a library every library root; nothing deeper, never the library). On the right a row hidden by Zotero’s setting carries (all windows) and a tooltip; ← Show brings it back in every window.
• A second main window (Ctrl+N) shows everything: the set is per window. Restart → each window gets its own set back, the first window included even with only its library tab open.
• Save & Close a window with something hidden → reopen it from the tabs menu → the same set. Switch tab sessions and back → each session’s windows have their own sets.

Popups (after touching popup code)

Run test/popups.spec.js first, then by hand:

• Comment popup and relations popup open anchored to their trigger, in the main window and in a standalone reader window.
• Second click on the same anchor toggles the popup closed.
• A click anywhere outside — including other documents/iframes — dismisses it.

Backlinks rows and count-popup rows: new window (after touching their click handling)

The specs drive synthetic clicks; a real Shift press and a real middle button are only checked by hand (2026-10-26).

• Backlinks section, a note row: Shift+click → the note opens in a note window, scrolled to the link, which flashes; a plain click → a tab.
• The same row with the middle button → a note window, and no autoscroll cursor appears.
• An annotation row (a link in an annotation comment): Shift+click → a reader window at that annotation.
• Tab to a row, Shift+Enter → a new window.
• Items list, click a Backlinks number, then middle-click a row in the popup → a new window, and the popup closes.
• Click a Related number; Shift+click a related paper → its PDF in a reader window; a related note → a note window; a paper with no file → selected in the library, as a plain click.

Backlinks on the children (after touching the attachment badge, the reader buttons or the by-part popup)

Backlinks part 2 (2026-10-28). test/backlinks.spec.js and test/count-popups.spec.js drive these with synthetic clicks and a hand-built PDF popup; the real pointer, the keyboard and the placement are checked by hand.

• Collapse a paper whose links aim at its children and click its Backlinks number: the popup is grouped by PART – “This item”, each file, the file’s annotations in reading order, each note – each heading with its share, the shares adding up to the title’s count; the rows under a heading carry no “→ …” chip. Expand the row and click again: the item’s own, no headings.
• Attachments section of that paper: a file that is linked, or whose annotations are, shows the backlinks glyph and a number right after Zotero’s annotation count, in the same grey; hover → “N Backlinks”; click → the same popup for the file. Tab to it, Enter and Space open it too. A file nothing links shows nothing. Settings → Backlinks off → the badges go; back on → they return.
• Write a link to that file in a note: the badge’s number moves within a second, without reselecting the paper.
• Reader tab: a linked annotation’s card carries a Backlinks button after Related, before ⋯. Click → the popup opens in the window holding the reader, right under the button; a second click closes it; a click anywhere else in the reader closes it too. The same in a standalone reader window.
• With the sidebar closed, click a linked highlight in the PDF: its popup carries the same button, after Related, before ⋯.
• With the reader open, add a link to one of its annotations in a note: the card’s button appears, or its count moves, without reopening the reader.
• Links buttons (2026-10-28, “Same also for links”): an annotation whose comment links another Zotero item shows the Links glyph (arrow out) just before Backlinks – on its items-list line while the Links column is shown, on its item-pane card, on its reader card and in its PDF popup; a web URL alone shows none. Click → “N Links” under a “This item” heading with its share. Turn Links off in Settings → the card and reader buttons go, back on → they return; the items-list icon follows the Links column, as the Backlinks icon follows its column.
• Any annotation popup (Links or Backlinks, from any of those places) looks like a collapsed paper’s: the “This item” heading with its share, then the rows (2026-10-28).
• A Links row aimed at an annotation (“→ annotation p. 4”) in a count popup shows that annotation’s highlighted text on one line with a bar in its colour; a row aimed at a paper or a file shows none, and the item pane’s rows show none at all. In the card, each annotation’s highlighted text has the same bar, in the normal text colour (2026-10-28).

Links section (after touching links.ts, the index or the shared row helpers)

test/links.spec.js drives the rows with synthetic events; the real pointer and the item pane’s own render are checked by hand (2026-10-27).

• Select a paper with a note that links other items: the Links section lists them under the note’s title, in the order they are written; a paper whose notes and annotations carry nothing reads “0 Links”, greyed. With broken references among them the header reads “3 Links · 48 broken” – the resolved count (what the column shows) and the greyed rows’ count, so the rows add up (2026-10-27); the broken ones sit in ONE collapsed “N broken links” row at the end of the section, each under the note or annotation it is written in – a source whose links are all broken is named nowhere else (2026-10-28) (click or Enter / Right to expand, Left to fold).
• The Links section sits right above Backlinks, in the item pane and in the side navigation (2026-10-27) – on a fresh profile, and again after Settings turns Links off and back on. A drag of a button in the side navigation (or the header’s right-click Move Section Up / Down) is the user’s own order and stays.
• Backlinks: a paper with links aimed at its children reads “0 Backlinks · 1 to its children” over the collapsed “1 more aimed at its …” row (2026-10-27).
• The section’s rows (Links and Backlinks, in the item pane and the context panes) carry no preview: icon, title, kind line and chip only – no excerpt, no annotated text (2026-10-28, “too small to show anything useful”). Click a count in the Links or Backlinks column: the popup’s rows keep the two-line excerpt with the link highlighted, and a row whose source is an annotation shows the annotated text, quoted and in italics, right above it (2026-10-27).
• With that PDF already open in a separate window and another of its annotations selected there: Shift+click the annotation’s row → the window shows the row’s annotation selected ALONE, not a range from the previous one (WV-TEMP-REG39, 2026-10-27). Same from the count popups and the Links section.
• The card’s arrow never crosses text: it leaves the source’s line, runs through the gap between the columns, and arrives along the target’s line (2026-10-27).
• Rest the pointer on a row → the card: SOURCE on the left (paper › file › annotation, or paper › note, each with Zotero’s icon; the annotation’s text), TARGET on the right climbed the same way (a broken one: “Item not found” + the address), and an arrow drawn from the note or annotation the link is written in to what it points at (the target’s deepest node); under both, across the card’s whole width, the reference’s kind and excerpt with the link highlighted, up to 600 characters before it (2026-10-28, “the link can use the full width”); move off → it hides. Tab to a row → the card at once; Esc hides it. The same card on Backlinks rows and in the count popups – there the TARGET is on the left and the source on the right, the arrow running back. Narrow the window under ~480 px: the two columns stack.
• Click a row aimed at a paper → the paper is selected; aimed at a note → the note opens in a tab; Shift+click → a note window; a middle click → the same, with no autoscroll cursor.
• A citation row → the cited item is selected; a quote row → the quoted annotation opens in its file.
• A link to a deleted item (or into a group this profile has not got): the row is greyed and says why; a click shows the link in its note; the header does not count it.
• Right-click a row → Show in Library, Copy Link, Show in Source, Add as Related; Show in Source opens the note scrolled to the reference, which flashes.
• A note tab: its context pane’s Links section is flat (no group head).
• With Better Notes enabled, a note tab shows both its Outbound Links and Weavero’s Links; neither breaks the other. A Better Notes link copied with Copy Link of Line or a section link reads “→ note line 3” / “→ note #Methods” in the Links row (alone, “→ line 3”, when the target is a standalone note), the position Better Notes’ own Outbound Links shows; clicking the row opens it there through Better Notes (2026-10-28; checked live on 3.3.3: the two sections list the same note-to-note link).
• Has External Link (2026-10-30, was Has Link): a note or comment with only zotero:// links no longer matches it (it is Has Item Links’s); one with an https://, mailto: or app link does, in the library, the reader and the annotations-pane funnels.
• Has Item Links (2026-10-28): the library filter’s tile sits between Has External Link and Has Backlinks; click it → the items whose Links column shows a number stay, a note or annotation that links an item is the matched row; Alt+click → the others. The reader funnel and the annotations-pane funnel carry the same tile (an annotation whose comment links another item); a web URL alone does not count. Turn Links off in Settings → the tiles go and a set chip stops filtering; back on → it applies again.
• The Links column (column picker, next to Backlinks): a paper’s number is its notes’ and annotations’ references together; expand the row → the paper’s cell goes blank and the note row carries its own; click a number → the popup lists the rows, a broken one greyed, under the Links glyph. Enable / disable the column in Settings → Extras.
• The hover card (Backlinks and Links) is opaque on the dark theme: the rows under it do not show through (2026-10-27).
• A paper with several files (PDF + EPUB…): its annotations’ group heads and rows read the annotation’s text, then in grey “File · p. N” (the file cut first, the page whole at any pane width; 2026-10-30), and “→ annotation” chips name the file in parentheses; a one-file paper’s show the page alone (2026-10-27), and so does a paper whose other files Zotero cannot annotate, e.g. a PDF + a Word file (2026-10-30).

Settings window buttons (Windows, after touching the Settings opener or its watcher)

The spec drives destroy/init directly; the real toggle goes through the Plugins Manager (2026-10-26).

• Weavero enabled, open Settings → minimize, maximize and close.
• With Settings still open, disable Weavero in the Plugins Manager → the open Settings window keeps only close (a maximized one is restored first); enable it again → minimize and maximize come back.
• Weavero disabled, open Settings, then enable Weavero → the buttons appear on that window.
• Plugins Manager open (Weavero enabled: minimize, maximize, close). Click Weavero’s own toggle and keep the pointer still → the card stays where it is, like any other plugin’s, and can be switched back on at once; the window is back to Zotero’s close-only title bar. Move the pointer off the list → the card moves to Disabled and the list narrows.

File / Edit menubar entries (macOS, after touching the window commands)

test/menubar-window-entries.spec.js proves the entries, their order and their gating on whatever platform runs the suite; the point of the feature is the Mac, where the hamburger does not exist and no Windows check can stand in. On macOS, by hand:

• File opens with New Tab… (⌘T), New Reader Window… and New Main Window (⌘N) as its first three entries, a separator under them, then Zotero’s New Item; the two shortcut glyphs render.
• Edit shows Advanced Search in New Window (“Shift+Click”) directly under Advanced Search.
• Each of the four does what its name says: the picker opens as a dialog; a new main window comes up clean; the Advanced Search window opens on the current collection with the search already open.
• Settings → Weavero → Tabs and Windows: untick Open new main windows → New Main Window and the Edit entry are gone on the next open of the menu, the other two stay, ⌘N / Ctrl+N does nothing, the hamburger (Windows/Linux) drops its New Main Window, the item menu its New Window row, and Shift+click on the funnel opens Zotero’s in-window search; untick the section master → all four entries gone. No restart in between.
• (Any platform, primary window maximized.) Edit → Advanced Search in New Window: the new window is NOT maximized – a modest window in the middle of the screen. Resize it, close it, open it again: it comes back at the size you gave it.
• (Any platform.) With “Hide the side panes in the Advanced Search window” on (the default): the Advanced Search window has no collections pane and no item pane; View → Layout brings one back there; the primary window’s panes are untouched, also after a restart.
• (Any platform.) The collections-pane button at the window’s top-left collapses the pane and stays exactly where it was (it re-homes from the collections toolbar to the items toolbar under the same pixels); a second press expands the pane; View → Layout → Collections Pane shows the matching tick and, used itself, leaves the button in place; the state survives a restart. Extras → Collections pane off removes the button at once.
• (Any platform.) Collections tree: with My Library selected, right-click another collection — My Library stays highlighted and the items list stays (no reload); the right-clicked row only shows a dashed outline while its menu is open; press Escape — outline gone, nothing else changed. Right-click → New Subcollection…: while the dialog is up nothing moves; Cancel — still nothing, the outline goes at your next click; Create Collection — you stay on My Library, the new subcollection appears with the dashed outline (gone at your next click). Rename Collection… → Enter — same: you stay, the renamed row keeps the outline until your next click. Right-click a saved search you are not on → Edit Saved Search — the search is selected at once (list and editor agree). Right-click a collection you are not on → Delete Collection… → confirm — the collection goes, you stay where you were. Right-click a saved search you are not on → Generate Report from Saved Search… — the report is that search’s (the list switches to it first). Right-click Group Libraries — no menu; middle-click it — nothing. Right-click → Open in New Window (first entry of the plugin section at the bottom, a separator under it when other plugins’ entries follow; Zotero’s own actions keep their places) — a new window on that collection, the first window still on My Library. Middle-click a collection — a new window on it, the first window unchanged, no selection change; Shift+click and Ctrl+click still select several collections (Zotero’s own gestures). Same with Multiple main windows off: middle-click and right-click behave as in plain Zotero except the restore, and the menu entry is absent.
• (Any platform.) Tick “Ctrl+Shift+F / ⇧⌘F opens Advanced Search in a new window”: the shortcut opens a new window on the current collection and the in-window pane stays closed; Edit now shows the shortcut on Weavero’s entry and none on Zotero’s. Untick: the shortcut opens the pane again and the shortcut text is back on Zotero’s line. Trusted key events cannot be scripted – this one is hands only.
• (Any platform.) Middle-click the Advanced Search funnel at the right end of the search box — the search opens in a new window, the same as Shift+click; the in-window pane stays closed. With Multiple main windows off the middle-click does nothing.
• A focused standalone reader window: its File leads with New Reader Window… and New Main Window (⌘N); New Tab… appears only when the window has Weavero’s tab strip (Hide title bar → reader windows). No Edit entry there.

Windows taskbar (multi-monitor, after identity/badge changes)

Follow the taskbar overlay matrix — minimum hand pass: S6 (drag across monitors without dropping), S7 (new window), and one fresh-reboot S13 run. Verify with your eyes (or screen captures), not logs: the failure modes are visible states the bookkeeping can believe it prevented.
