The sidebar pins navigation above a scrollable session list split into **Pinned**, one section per custom group (the session `category`), and **Ungrouped** for the rest. Every active session loaded for the selected agent stays visible inline; opening a session moves the selection highlight without reordering the rows. Sessions with new activity since they were last read show an unread dot, and opening one marks it read. Each session row has a context menu (kebab button or right-click) with Pin/Unpin, Mark as unread/read, Rename, Fork, Move to group (including New group and Remove from group), Archive, and Delete; touch layouts keep the direct pin and menu controls visible. Drag a session onto a custom group or **Ungrouped** to move it. Group headers can be collapsed, expanded, or dragged to reorder them; the collapsed state and custom order are stored in the current browser profile. Group headers also have a menu (kebab button or right-click) with Rename group, New group, and Delete group; renaming or deleting a group updates every member session, including archived ones, and deleting a group keeps its sessions and moves them back to Ungrouped. Groups created from the header start empty and stay visible as move targets. The sort control in the session list header also has a Group by toggle: Custom groups (default) or None for one flat list (Pinned stays separate); the choice is stored in the current browser profile. Multi-agent setups show a compact scope control in the session-list header. **Overview** is the only destination pinned by default; expand **More** to reach every other destination. Select **Customize sidebar** under More, or right-click the navigation area, to pin or unpin destinations and restore the defaults. The pinned set and More expansion state are stored in the current browser profile and survive reloads.

- The sidebar lists every loaded active session by pinned/custom/ungrouped section with a New Session action. Opening a visible row moves only the highlight. Custom groups are collapsible and drag-reorderable, and sessions can be dropped onto a group or Ungrouped; the browser preserves the group order and collapsed state across reloads. A new dashboard session asynchronously gets a concise generated title from its first non-command message; explicit names are never replaced. Set `agents.defaults.utilityModel` (or `agents.list[].utilityModel`) to route this separate model call to a lower-cost model. Switching the compact agent scope shows only sessions tied to that agent and falls back to that agent's main session when it has no saved dashboard sessions yet.

- Session search lives in the command palette (⌘K, or the Search field at the top of the sidebar): typing a query follows a bounded number of matching pages across agents, filters internal child/cron rows, and lists visible matches next to navigation commands. The Sessions page keeps the exhaustive searchable list with filters.
