   A first slice — list data and inbox grouping — is implemented on my fork, ready to retarget here after sign-off: alexandre-vl#1 (diff against main).

   • Typecheck, lint, 54 tests and scripts/check-plugin-forks.mjs pass.
   • On get-bb/bb the list request costs 6 GraphQL points instead of 5, still one request per repository per sweep.
   • bb github prs prints the same next step; --json adds nextStep and pr.

   Prototype update, same link: https://alexandre-vl.github.io/bb/prototype/. Menus now open at their trigger, and every read and write has a loading state you can watch.

   Menus open at their trigger

   Two menus were misplaced. The reply target menu was laid out inside the composer and made it taller. The display menu opened at the window's right edge, over the pull request.

   	Before	After
   Reply target (#5849)
   Display menu
   Display menu, phone

   • Every menu opens 4 px from its button and lines up with the button's edge: display, reply target, the row ⋮ menu, snooze, and the thread header chip. Near a screen edge, a menu flips to the other side or is clamped to stay on screen. The composer keeps its height.
   • When the panel is narrower than 560 px, a menu opens as a bottom drawer over a scrim.
   • Dialogs no longer replay their entrance animation when the list re-renders behind them.

   Loading

   Reads and writes now take time in the prototype, so each loading state can be seen. The prototype adds none of its own loading patterns: each state uses something bb already ships.

   

   The recording: first load, then Refresh. The agent fixing #5835's checks has finished, so its row moves into Ready to merge.

   When	What you see	From bb
   First load	Nothing for 200 ms. Then skeleton rows at the real row and group heights, which fade out over the loaded rows.	DelayedLoading, Skeleton, stable dimensions, abstract bars
   Opening a pull request	The header appears at once, from the list row. Activity, Files and Checks each show a skeleton until their own request returns, and are cached after that.	preserve panel geometry
   Refresh	The rows stay. A 2 px indeterminate bar runs under the header, and Refresh spins and is disabled. A row whose state changed slides to its new group and flashes.	route navigation indicator
   Merge	A loading toast, which becomes the success or error toast. The row shows a spinner and Merging into main… with the shine bb uses for Checks running.	appToast.loading, then the same id, running: true, animate-shine
   Launch an agent, re-run checks	The button is disabled, marked aria-busy, and shows a spinner. Re-run checks then tick through live.	pending control
   Reply, mark ready, snooze	Applied at once. A reply reads sending…; if it fails, it reads couldn't send and offers Retry.	optimistic send
   Offline	Can't reach GitHub with Try again. With rows already on screen, a banner says they come from the last sync. The list reloads when the connection returns.	—

   To try it, use the bar above the prototype: Replay loading empties the cache and loads everything again, Slow network makes every request about 3× slower, and Offline makes every request fail. #net=slow and #net=offline open the prototype in those modes.

   The prototype departs from bb in one place. Skeleton has no exit transition, so in bb the content replaces it in a single frame. The prototype instead fades the skeleton out over 150 ms, above rows that are already laid out; drop that if you prefer bb's swap. With reduced motion, spinners and skeletons stand still and rows don't slide.

   Each loading state

   First load, 650 ms in	Opening #5839
   Merging #5856	Refresh in flight
   After the refresh	Offline
   Phone, first load

   Prototype update, same link: https://alexandre-vl.github.io/bb/prototype/#pr=5849. The pull request status is now a menu, and the diff stat uses bb's own colours.

   The status is a menu

   Today the status pill only labels the pull request, so changing the status means going to GitHub. In the prototype, clicking the pill or pressing S lists the four states and what picking each one does.

   

   Picking Draft on #5849: the pill spins, the toast resolves with Undo, and Activity records the change.

   Before	After

   The status menu on #5849	After choosing Closed

   

   On a phone the menu is a bottom drawer.

   • Draft and Open (ready for review) behave like core's own buttons for a thread's pull request: a pending state, then a loading toast that becomes the success toast (handlers, banner buttons). Here the pill shows the spinner, and the success toast offers Undo.
   • Merged opens the merge dialog when GitHub can merge the pull request. Otherwise it stays disabled and says why: 2 checks failing, Conflicts with main, Mark it ready first.
   • Closed asks for a second click within 3 s. The pull request then leaves the inbox, its next-step card offers Reopen, and it moves to a collapsed Closed group under All.
   • Each change is recorded in the Activity timeline, and the row moves if its group changes. Offline, the change fails with an error toast and nothing moves.
   • The icon and colour for each state come from core's PULL_REQUEST_STATE_DISPLAY. Merged pull requests keep a static pill.

   For any listed pull request, the plugin would call GitHub's markPullRequestReadyForReview, convertPullRequestToDraft, closePullRequest and reopenPullRequest. It would offer each state only when the pull request reports viewerCanUpdate, viewerCanClose or viewerCanReopen.

   Diff stat and branch

   • +74 -14 takes the text-diff-added / text-diff-removed colours from DiffStatsTally and the five blocks from DiffSizeBar. Clicking it opens the Files tab. Rows (Show on rows → Changes) and the Files tab use the same colours.
   • The head branch is a copy chip: clicking it copies the name, and its icon turns into a check for 1.6 s.

   Smaller fixes

   • Mark ready and Convert to draft in the row menu used to only show a toast. They now change the pull request, and the menu has Change status… (S).
   • Arrow keys, Home and End move through every menu. Before, the arrows moved the list selection behind an open menu. Esc on the status menu returns focus to the pill.

   🚨 SLOP COP 🚨 · new-issue-autopilot

   Applied missing classification: Type: Feature · Priority: Medium · Effort: High. Added labels: ui, github. No existing classification values or labels were replaced; all writes were verified.

   This adds a PR inbox and agent-handoff workflow rather than correcting a single unexpected behavior. Existing detail views and GitHub provide workarounds; the proposed grouping, actions, thread linkage, and ambient surfaces require substantial interaction design and integration.

   No reproduction report or pull request: this is a feature request requiring product/design decisions, outside the bug-only fix path.
