I often have multiple sessions running.
It would be nice to get a quick list of active sessions.
This would be nice as a whole, not just per project.

Active here can mean 2 things and I think both are useful:

1. Interacted with recently (like say... in the last hour) but may currently be idle.
2. Agent session is actively doing something and I'm waiting for a result.

| Field | Value |
| --- | --- |
| App version | 1.0.17 |
| OS | NixOS 26.5.0 |
| Theme | GitHub |
| Path | /chat |
| Tenure | Week 6 |

Start from the /chat path in the app and trace how sessions are represented and scoped across projects. Define a quick list that covers both recently interacted sessions and sessions currently doing work, with behavior confirmed against the reported use case.
