What it does
- Per-module and per-space threads; system lines mark actions.
- The Messages inbox (beside the bell) collects every thread: Discussion and Notes tabs, unread counts, reply in place, mute per thread.
How to use it
- Comment on the module; triage from the inbox.
Best used for
- "Which dates work?" next to the actual calendar.
Smart touches
- Mute the noisy thread, not the whole app.
