Summary

Reworks the v2 Workspaces page around devices and fixes the interaction lag on its header controls.

  • Device on every list row: restores the device item removed with the Host column in feat(desktop): rework Workspaces page into a status-grouped triage list #6506 — laptop/monitor icon + host name before the timestamp, dimmed with a grey dot when a remote device is offline (matches the board card's vocabulary).
  • Device-first header: the page title is now the device filter dropdown (real machine name, other hosts with online dots), with a primary Create workspace button opposite; the title row doubles as the window-drag surface. Second row: bare borderless search on the left; first-class project filter (selected project's icon in the trigger) plus compact Filter / Display / List–Board controls on the right. The archived-window control moved back under Display.
  • Created-by filter: new "Created by" submenu in the Filter menu (avatars, "(you)" marker), wired through the filter store, row filtering, and the URL as ?creators=.
  • Perf, measured over CDP against the running app:
    • Filter-checkbox toggles painted in 300–515ms (all 200+ rows re-rendered synchronously behind the open menu). memo() on rows/cards + useDeferredValue on the list data + modal={false} on the header menus → checkbox paints ~143ms with the list catching up off the critical path; menus no longer scroll-lock the page.
    • Typing in search cost 76–197ms per keystroke, ~40% of it the dashboard sidebar re-rendering because the URL synced (navigate()) on every key. Debounced the URL sync (300ms) + deferred the search query into the filter hook → 5–12ms per keystroke.

Test plan

  • Typecheck (tsc --noEmit) passes
  • CDP end-to-end in the dev app: device dropdown opens/lists hosts; Created-by toggle filters rows (238→175) and round-trips the URL; project icon renders in the trigger; search focus shows no ring/background
  • Latency re-measured after each fix (menu open 41ms; checkbox paint 515→143ms; keystroke processing 197→12ms)
  • Sanity-check board view drag/menus after the memo()/non-modal changes

Summary by cubic

Reworks the Workspaces page around devices, adds a Created-by filter, and fixes the lag in filter menus and search typing.

New Features

  • List rows show the host device again: laptop icon for the local machine, monitor for remote, dimmed with a grey dot when a remote device is offline.
  • The page title is now a device filter dropdown showing the actual machine name, with a "Create workspace" button opposite it.
  • Added a "Created by" submenu to the Filter menu with avatars and a "(you)" marker, synced to the URL as ?creators=.
  • The project filter is a first-class trigger showing the selected project's icon; the archived-window control moved back under Display.
  • Search is now a bare borderless input with no focus ring.
  • Container-query variants let the toolbar and rows compact for narrow panes: Filter/Display/List/Board go icon-only, the device item shrinks to its glyph, and diff stats hide.

Bug Fixes

  • Filter checkbox toggles took 300–515ms because every row re-rendered synchronously; memoized rows/cards, deferred list updates, and non-modal menus cut checkbox paint to ~143ms.
  • Each search keystroke cost 76–197ms because URL sync re-rendered the whole app; debounced sync (300ms) and deferred search cut it to 5–12ms.
  • Board view drag and menus still need a sanity check after the memoization and non-modal changes.

Written for commit 058a01c. Summary will update on new commits.

Summary by CodeRabbit

  • New Features

    • Added creator-based workspace filtering with creator names and workspace counts.
    • Promoted device and project filters to prominent controls.
    • Added a “Create workspace” button and moved search to the top toolbar.
    • Workspace rows now display device details and offline status.
    • Filter selections are preserved in the URL.
  • Performance

    • Improved responsiveness during workspace filtering and searching.
  • UI Improvements

    • Device labels now show the local host name.
    • Updated filter counts, clear-filter behavior, dropdown alignment, and view controls.
    • Improved workspace layouts for narrower panels.

The #6506 triage-list rework dropped the Host column, leaving no way to
tell which device a workspace lives on from the list view. Bring it back
as a compact item before the time label, matching the board card's
vocabulary: laptop icon for this device, monitor for remote, dimmed with
a grey dot when a remote device is offline.

Claude-Session: https://claude.ai/code/session_01MvYMxnyovLCDNBdDrLqis3
Rework the Workspaces toolbar around the device, matching the reference
design: the page title is now a first-class device dropdown showing the
actual machine name (All devices / this device / other hosts with online
dots), with a primary Create workspace button opposite it. The second
row keeps search on the left and promotes the project filter ("In all
projects") and archived window ("Hiding archived") to first-class
dropdowns beside the remaining Filter/Display/view controls. Device,
project, and archived leave the Filter and Display menus accordingly,
and the title row doubles as the window-drag surface.

Claude-Session: https://claude.ai/code/session_01MvYMxnyovLCDNBdDrLqis3
…page

Add the creator filter the page never had: a Created by submenu in the
Filter menu (avatars, '(you)' marker), backed by creatorFilters in the
filter store, matched in useAccessibleV2Workspaces, and synced to the
URL as ?creators=.

Style pass on the header: the search input drops its background/shadow
pill to bare icon+placeholder (WorkItemsSearch gains containerClassName
so the magnifier sits on the same 24px rail as the title icon and row
content), and the List/Board toggle matches TasksTopBar's borderless
muted pill.

Claude-Session: https://claude.ai/code/session_01MvYMxnyovLCDNBdDrLqis3
…focus

The Hiding archived control leaves the Workspaces toolbar; the archived
window moves back under Display where it lived before. The search input
also loses its focus ring so the focused state stays as bare as the
resting one.

Claude-Session: https://claude.ai/code/session_01MvYMxnyovLCDNBdDrLqis3
…gger

Toggling a filter checkbox took 300-515ms to paint because every change
re-rendered all 200+ rows synchronously behind the open menu. Three
fixes measured over CDP:
- memo() on V2WorkspaceRow and V2WorkspacesBoardCard — workspace object
  identities are stable across filter changes, so unchanged rows skip.
- useDeferredValue on the list/board workspaces — the checkbox paints
  at ~140ms while the list catches up at background priority (~350ms),
  off the interaction path.
- modal={false} on the header dropdowns — no more body scroll-lock and
  pointer-events dead zone while a menu is open.

The project dropdown trigger now shows the selected project's icon
(terminal glyph for Sessions, folder when unfiltered or multi-select).

Claude-Session: https://claude.ai/code/session_01MvYMxnyovLCDNBdDrLqis3
Profiling real keystrokes showed 76-197ms of main-thread work per
character, ~40% of it the dashboard sidebar: the filter URL sync called
navigate() on every keystroke, and each navigation re-renders every
router-state subscriber app-wide. Two changes, measured over CDP:
- Debounce the URL sync 300ms — one trailing navigation after typing
  stops instead of one per key. The URL is only a deep-link mirror.
- useDeferredValue(searchQuery) into useAccessibleV2Workspaces so the
  filter recompute happens at background priority off the keystroke's
  critical path.

Per-key processing drops to 5-12ms.

Board cards and list rows use memoization. List rows display host details and remote-host offline status.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 058a0

The Workspaces redesign adds device metadata and creator filtering, but narrow layouts may hide device names from keyboard and screen-reader users, while creator-only filters with no matches can show the wrong empty state and hide the clear-filter action. The PR is mergeable with owner awareness and follow-up on these bounded issues.

Include creator filters in the list empty-state condition.

If a creator-only filter returns no rows, V2WorkspacesList reports “No workspaces yet” and hides its Clear filters action. Add creatorFilters.length > 0 to hasActiveFilters in apps/desktop/src/renderer/routes/_authenticated/_dashboard/v2-workspaces/components/V2WorkspacesList/V2WorkspacesList.tsx.

Proposed fix
+	const creatorFilters = useV2WorkspacesFilterStore(
+		(state) => state.creatorFilters,
+	);
+
 	const hasActiveFilters =
 		searchQuery.trim() !== "" ||
 		deviceFilter !== DEVICE_FILTER_THIS_DEVICE ||
 		projectFilters.length > 0 ||
 		prStateFilters.length > 0 ||
 		agentStatusFilters.length > 0 ||
+		creatorFilters.length > 0 ||
 		pinFilter !== "all" ||

At narrow widths the List/Board toggle clipped off the toolbar edge and
row names truncated while ~260px of metadata held firm. Container-query
compaction (@max-* variants):
- Toolbar under @2XL: icon-only Filter/Display/List/Board (the filter
  count badge stays), tighter project label.
- List rows (scroller is now a @container): the device item drops to
  its glyph under @2XL (full name stays in the hover title) and diff
  stats hide under @lg, giving the name the room back.

Verified over CDP at 700/760px (nothing clips) and full width
(unchanged).

Expose the host name through an accessible path.

At widths matching @max-2xl:hidden, the host name is hidden. The remaining title is attached to a non-focusable <span>, so keyboard and screen reader users cannot reliably inspect workspace.hostName. Add an accessible label or an accessible tooltip for the device metadata.

Real PR descriptions routinely embed raw HTML — bot-generated badges
(<a><picture><source><img>), <sup> commit notes, <details> spoilers —
alongside plain markdown, and HTML comments to hide metadata markers.
The previous renderer escaped all of it into visible "&lt;sup&gt;" /
"&lt;!-- ... --&gt;" garbage instead of rendering it. Now:

- HTML comments are stripped, not shown.
- A fixed allowlist of tags (a, img, picture/source, details/summary,
  table, sup/sub, etc.) renders as sanitized real markup — attributes
  outside a per-tag allowlist are dropped, href/src schemes are
  restricted to http(s)/mailto, and any <a> always gets a forced
  target="_blank" rel="noopener noreferrer" regardless of what the
  source specified. Everything else still falls through to plain-text
  escaping, unchanged.
- Multi-line raw HTML (badge blocks, collapsible sections) is detected
  and consumed as one block, terminated at the next blank line.
- `- [x]`/`- [ ]` task-list items render as real disabled checkboxes
  instead of literal bracket text.

Verified against the real HTML in superset-sh/superset PR #6901's
description (cubic.dev/CodeRabbit bot summaries) in a live browser.
