   This issue might be a duplicate of existing issues. Please check:

   • [FEATURE]: Persistent right-side message navigation sidebar in the desktop app session view #32999: Persistent right-side message navigation sidebar listing user messages with click-to-scroll — very similar scope (sidebar nav, jump-to-message, truncated question text)
   • [FEATURE]: Conversation outline / prompt navigation for long chats #40826: Conversation outline / prompt navigation panel for long chats — same core problem of navigating long sessions by user prompts

   The per-message color dye / hover preview aspect of your proposal appears to be new, but the navigation foundation overlaps significantly with these open requests. You may want to comment on one of them instead, or clarify what makes this distinct beyond the color/preview additions.

   Not a duplicate - complementary to #32999 and #40826.

   Those propose a new sidebar/panel. This proposes extending the existing MessageNav component both panels would use:

   • getPreview(msg) -> { question, answer, time, model } for hover preview
   • dyeStorageKey for per-message color dot persisted in localStorage
   • fully opt-in, default render unchanged

   If #32999 lands, it can consume these props instead of plain truncated text. Happy to rebase onto it. Scope is message-nav.tsx/.css + session.tsx wiring only.
   Verified on latest dev: no Messages tab in SessionSidePanel, so #32999/#40826 are unimplemented proposals.

   Thanks for the detailed proposal, @xf2214! To restate it: you'd like MessageNav to optionally show a hover preview for each user message (question, answer, time, model) and let you mark messages with a colour dot that is saved per session, so long sessions are easier to scan. With the props omitted, nothing would change.

   Maintainers will consider it. Since there's a lot of parallel work on session navigation right now, it's worth waiting for their feedback on the direction before opening the PR. Related issues and PRs:

   • feat(app): add session turn navigator #54088: open PR adding a session turn navigator with hover previews of the prompt and the end of the latest reply. This overlaps with the preview part of your proposal.
   • feat(app): add prompt navigation rail to the session timeline #57869: open PR adding a prompt navigation rail to the session timeline.
   • [FEATURE]: Left-edge prompt navigation rail using MessageNav #52500: left-edge prompt navigation rail using MessageNav.
   • [FEATURE]: Keyboard jump-to-message list in the desktop/web session view #55672: keyboard jump-to-message list in the desktop/web session view.
   • [FEATURE]: ChatGPT-style prompt navigation (user message table of contents) in the desktop session view #54290: ChatGPT-style prompt table of contents (closed).

   As far as I can tell, none of these covers per-message colour markers, so that part is new.
