Sidebar view filtered to agent activity (a third sidebar mode)

[Serginyo90]

With many sessions across workspaces, only a few have an agent doing something at any moment. The flagged view solves this for a hand-picked set; I'd love the same flat view for "where are my agents right now" — without flagging/unflagging by hand.

Proposal

• A third SidebarMode next to tree/flagged: a flat list of every session whose agent status is non-idle (working / waiting for input / finished), in tree order (stable — rows only appear/disappear as statuses change, no live re-shuffling).
• Rendering clones the flagged view: session : workspace rows with the existing status glyph and badge, no drag-reorder, an empty-state hint.
• A second bottom-bar toggle button next to the flag one; modes stay mutually exclusive. Plus the usual View menu / ⌃⇧P palette / BuiltinAction mirrors of the flagged toggle.
• Session navigation, Ctrl-Tab, and the ⌃P palette scope to the filtered set automatically via navigableSessions, like flagged mode.
• Control API: sidebar mode attention (read-back via the existing sidebarMode field).
• A session whose status clears drops out of the list; if it was selected, same stranded-selection behavior flagged mode already has.

Open questions

• Name: attention (matches the attention popover/nav set) or activity?
• Include completed, or only active + blocked?
• Tree order vs urgency (blocked-first) order? I'd propose tree order for stability — the glyphs already show urgency.

Happy to implement and send a PR (tests, agent-skill docs, README/site included) if this fits agterm's direction.

Already implemented in different way

the find-and-jump part of this already exists, from three angles, all reading the same non-idle set across workspaces (sorted blocked → active → finished, with the status glyph):

• the title-bar bell popover: a clickable list of every non-idle session, click a row to jump (and it reveals the blocked pane). This is essentially the flagged-view rendering, minus the sidebar slot.
• the attention palette: ⌃⇧I (also Navigate ▸ Go to Attention…, or ⌃⇧P → "Show Attention"), same set, searchable.
• attention-nav: ⌃⌥↑/↓ steps through the blocked/finished ones and wraps.

so the gap you're really after isn't find/jump, it's a persistent roster you can glance at while working instead of opening a popover that dismisses. That part is real, none of the three leaves a standing list on screen.

but a third SidebarMode is the wrong shape for it. Modes are mutually exclusive, so you'd have to give up the workspace tree to watch the attention list, whereas the bell popover overlays the tree without replacing it. And unlike the flagged set (which only changes when you flag/unflag a row), agent status flips on its own, so a pinned attention view would add and remove rows under the pointer as sessions go working → waiting → finished → idle. The flagged view is deliberately stable for that reason; the attention set isn't.

and if you want a standing multi-session view rather than a popover, the dashboard is already scriptable for exactly this. dashboard takes explicit session ids and tree reports each session's status, so a custom keybind command that opens a grid of just the non-idle sessions is a one-liner:

agtermctl dashboard $(agtermctl tree --json | jq -r '.. | objects | select(.status? and .status != "idle") | .id' | head -9)

that gives you the ambient "where are my agents right now" view today, no new mode. So I'm not going to add the third sidebar mode. If find/jump plus a scripted dashboard still leaves a real gap, tell me what specifically falls short.
