fix(web): make long expanded queues easier to scan by diddletime · Pull Request #26026 · pingdotgg/t3code

diddletime · 2026-10-27T16:46:04Z

With 20 multi-paragraph messages, the expanded queue becomes a long column of full chat bubbles. The browser fixture occupied 3,548 px before this change.

Limit the expanded queue to half the viewport height and show numbered, two-line previews. Each message can expand to show its full text. The small collapsed queue keeps its current layout.

Fixes #25952.

Verified with vp run check:changed and a 20-message fixture in the isolated Browser panel, including expanding and collapsing a message. At an 800 px viewport height, the expanded queue occupies 400 px.

Created with gpt-6-astra-ultrafast in Codex through T3 Code.

Walkthrough

The expanded queued-message list now uses numbered, two-line previews with per-message disclosure for full text. In compact mode, the list has a height limit and vertical scrolling, and message cards use the full available width.

Changes: Queued message preview

Layer / File(s)	Summary
Preview and expanded-list layout `apps/web/src/components/chat/QueuedRunsControl.tsx`	When the queue is collapsible and “Show all” is active, each row displays a numbered, two-line preview with a disclosure for the full message. The list gains a height limit and scrolling, and cards use the full available width. Otherwise, messages display in full and cards keep their previous width limit.

Full details: Description check

Explanation

The description covers the problem, implementation, linked issue, verification steps, observed results, screenshots, and agent attribution. It does not state explicit maintainer approval or explain an approval exemption, but the remaining required information is complete enough for this focused fix.

Full details: Linked Issues check

Explanation

The change addresses issue #25952. When the queue is collapsible and showAll is active, QueuedMessageText renders numbered two-line previews with independent native <details> expansion. The expanded list uses max-h-[50dvh] and scrolling. The full message remains available in each expanded item. Non-expanded and non-collapsible rendering keeps the existing paragraph layout. The issue defines no additional automated-test coding requirement.

Full details: Out of Scope Changes check

Explanation

The diff changes only apps/web/src/components/chat/QueuedRunsControl.tsx. The added component, compact queue styling, numbering, preview, disclosure, and height limit directly support issue #25952. No unrelated behavior or files are changed.

QueuedRunsControl so its accessible name includes the message preview and

preview remains in the accessible name.
- Around line 315-320: Update the render condition for QueuedMessageText so

Preserve the message preview in the disclosure name.

This aria-label replaces the visible preview in the accessible name. A screen reader announces only Read queued message N, so the user cannot identify the message without opening it. Remove the label or make it include the preview and reflect the open state.

Keep image-only compact rows numbered and expandable.

Image references are removed from previewText, so the existing guard omits QueuedMessageText for compact image-only rows. The row still has an accessible queue label, and the thumbnail supplies the image name, but neither provides the visible numbered disclosure or a full-message path.
