📝 WalkthroughSummary by CodeRabbit
WalkthroughThe thread view now renders messages in chronological order and can hide middle messages behind an expansion control. Shared utilities handle unread targeting, expansion rules, DOM-based alignment, reveal scrolling, and page navigation. Email interactions use post-layout reveal behavior and updated keyboard handling. Collapsed rows and message headers use filtered click handling, date tooltips, focus styling, and new macro-thread layout utilities. Merge Risk: 🔵 Low · up to The PR changes how email threads expand, scroll, and respond to keyboard input, with user impact limited to presentation and navigation behavior. It is mergeable with owner awareness and follow-up for the clickable-row cursor styling and code-conformance issues. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

In `@apps/web/src/features/block-email/component/Email.tsx`:
- Around line 196-218: Update revealTargetMessage to invoke
performScrollToMessage(messageId, { align: 'start' }) from a layout-safe
callback after the target message is present and rendered, including after
loadMessagesUntilFound completes when needed. Preserve the existing expansion
and loading behavior, and do not rely on revealMessageAfterLayout alone because
the target ID must be cleared by performScrollToMessage.
In `@apps/web/src/features/block-email/component/MessageList.tsx`:
- Around line 230-234: Update the hidden-message label near truncatedMiddleCount
so it uses singular “message” when the returned count is 1 and plural “messages”
otherwise; preserve the existing count and display behavior for all other
values.
- Around line 93-112: Update MessageList’s onscroll pagination flow to preserve
the viewport when older messages are prepended: capture the list’s scrollHeight
before fetchNextPage, await the fetch, then increase scrollTop by the resulting
scrollHeight delta. Retain the existing scrolling and initial-load guards, and
ensure the adjustment occurs only for the older-message fetch triggered by the
threshold.

Match Gmail’s middle truncation and land at the visual top instead of auto-scrolling. Collapsed rows scan as a name / preview / date grid, and keyboard focus uses the same list fill as inbox. Co-authored-by: Cursor <cursoragent@cursor.com>
The expand chip should keep the same edge as before, and collapsed dates should show the full timestamp on hover like open cards. Co-authored-by: Cursor <cursoragent@cursor.com>
Use a normal column so load starts at the top, let header clicks collapse even the newest card, and drop expand/collapse scroll compensation. Co-authored-by: Cursor <cursoragent@cursor.com>
Give every message its own bordered card and a comment-style focus shadow, instead of a flush stacked list. Co-authored-by: Cursor <cursoragent@cursor.com>
The control already shows its label, so the tooltip was redundant and the full-width ghost wash clashed with the text chip. Co-authored-by: Cursor <cursoragent@cursor.com>
A slightly darker outline marks the active card without boxing every open message. Co-authored-by: Cursor <cursoragent@cursor.com>
Disable overflow anchoring so opening a message grows down, then scroll only if the open card would be clipped. Co-authored-by: Cursor <cursoragent@cursor.com>
Stop outdenting cards below 816px so mobile and tablet keep a side gutter, and drop the radius clamp that squared corners. Co-authored-by: Cursor <cursoragent@cursor.com>
After reply and collapse, Escape drops the focused card so the rail and shadow only show when something is selected. Co-authored-by: Cursor <cursoragent@cursor.com>
Instant jumps felt harsh; match keyboard navigation when the list has to move. Co-authored-by: Cursor <cursoragent@cursor.com>
Down and Up scroll the focused message while it overflows, then nearest-align the next card only if it is offscreen. Co-authored-by: Cursor <cursoragent@cursor.com>
Keyboard and deep links still walked hidden middle rows, and bg-message stayed at the panel color because Layer remapped lift but not --color-message. Co-authored-by: Cursor <cursoragent@cursor.com>

Older lazy-loaded messages were shoving the card you were reading. Deep links now land that card at the top. Co-authored-by: Cursor <cursoragent@cursor.com>
Negative outdent was pulling cards past the title gutter. Co-authored-by: Cursor <cursoragent@cursor.com>
Island cards already separate the header from the first message. Co-authored-by: Cursor <cursoragent@cursor.com>
Rail reads too heavy on island cards. Edge sits between idle muted and the thread path. Co-authored-by: Cursor <cursoragent@cursor.com>
Arrow keys treat the expand control as a list stop, and selected uses the same wash as a channel cursor so it does not linger after you leave. Co-authored-by: Cursor <cursoragent@cursor.com>
Enter on the chip was clearing selection. Land on the first revealed card so Arrow can keep walking. Co-authored-by: Cursor <cursoragent@cursor.com>
Up on the oldest message was a no-op when the title sat above the viewport. Page to the top first, then clear selection. Co-authored-by: Cursor <cursoragent@cursor.com>
The one-line grid left almost no room for the preview on a phone-width card. Name and date stay on the first row; the snippet gets two lines underneath. Co-authored-by: Cursor <cursoragent@cursor.com>
Replace the next/prev helper chain with a shown-stop sequence so Arrow keys share one reading order. Name collapsed-row slots instead of child indexes. Co-authored-by: Cursor <cursoragent@cursor.com>
