Sessions
With a project open, chats are saved automatically. Recent in the sidebar lists sessions for this project; click one to switch.

On the desktop
- New chat: top of the sidebar, starts another session.
- Switch: click a title in the recent list.
- Rename / delete / export: the menu on a session row. Export HTML to share or keep a record.
- Configuration edits can be exported as their own change log.
Sessions in the same project stay separate; check which one is active before changing configuration.
