- Sidebar chat titles shimmer while the agent works, replacing the
spinner (the archive affordance keeps its hover slot).
- Chat projects use the Notebook icon family instead of folders
(sidebar groups, project picker, new/none rows).
- Right-click on any chat offers Rename (dialog writing owner
metadata — hidden on shared chats), Pin/Unpin (persisted per
workspace; pinned chats sort to the top of their section), and
Archive.
- Solo chats (you plus one agent) hide the agent's avatar and name so
replies read as a plain stream; identities return automatically the
moment another agent or person participates.
The switching e2e now covers the context menu, pinning order, and
rename round-trip.
