The sidebar

The sidebar lists every open session, grouped so that whatever needs you is near the top.

The sidebar: pinned sessions, then those needing you, working, and parked

Group Holds
Pinned Sessions you pinned with m, in the order you pinned them. '1 to '9 jump to them.
Needs you Blocked or asking: an agent waiting on you.
Working Agents busy on their task.
Parked Sessions you set aside with zz, and finished ones.

Each row shows the session's state glyph, its title, its repos (one chip per worktree, then one per repo it opened a PR in), the agent and what it is doing, and how many pull requests it tracks. The numbers on the left are relative to the cursor, as in vim: the number on a row is how many j or k presses away it is.

The footer counts repos and worktrees; gr opens Repos.

zs collapses the sidebar to a narrow rail: one row per session with its number, state and pin, so moving and jumping still work. zs again brings the sidebar back.
