Love this. Easily the most annoying thing about modern Agent development across Claude, Codex, etc. One nit: You don't auto-discover "archived" chats from Codex. They have to be unarchived and the app restarted before being found.
I'll add support for this. On another note, if you know what the issue is, our core is open and I would love for you to contribute: https://github.com/skillsynchq/txcript
