Clean up and improve how comment threads are structured and displayed on patches and issues.

Show comment actions only on hover

Hide the edit/react/reply icon row on comments by default and reveal it when the comment is hovered or focused, reducing visual noise in threads.

Remove duplicate reaction selector

Comments with existing reactions showed a second reaction picker next to the reactions row, duplicating the one already in the header action row. Dropping the redundant one.

Highlight own reactions on comments

Give emoji reactions a distinct pill style and visually mark the reactions the current user has participated in with a subtle background, so they stand out from reactions left by others. Also renders the emoji glyph at the same 16px size used by other UI icons instead of the 12px text size.

Indent replies and render them in individual boxes

Give each reply its own framed box so replies read as discrete items instead of a merged column. The replies section now also indents from the parent comment and adds a pair of timeline lines along its left edge — one continuing the main thread connector and another stub at the reply-avatar position — to visually group replies under their parent in deep threads.

Drop “drag and drop files” hint from comment form

Surface submit shortcut on the submit button itself

Move the keyboard shortcut hint from the helper text below the comment form onto the submit button as a dimmed suffix, drop the now-redundant “Press ⌘↵ to submit” phrasing, and remove the checkmark icon so the button reads as text plus shortcut only.

Hide comment form footer until text is entered

For the always-open comment form at the bottom of a thread, collapse the action row (discard, markdown hint, attach, preview, submit) while the textarea is empty so an unused form doesn’t clutter the discussion. The row reveals as soon as the user starts typing.

Align reactions row with comment author padding

Match the reaction row’s left inset to the author row’s and add a touch more breathing room below it when reactions are present.

Polish reaction controls

• Reactions fade their background on hover to signal interactivity.
• Hovering a reaction the viewer has made shows a “Remove reaction” tooltip instead of the author list.
• When a comment has reactions, the emoji picker moves from the hover-only header row to the right of the reactions list, where it also stays hover-only.
