Hey! Just wanted to connect some related work here:

Existing implementation:

• feat: add subagents sidebar with clickable navigation and parent keybind #4865 - Already implements a subagents sidebar (created Nov 28, before this issue). Shows subagents in a collapsible list with click-to-navigate functionality and parent keybind. Has been battle-tested in shuvcode (an unofficial fork) where it was merged as Sidebar fix Latitudes-Dev/shuvcode#97.

Alternative approach:

• Feature Request: Agent Session Tab Bar Navigation #5826 - Proposes a horizontal tab bar at the top (similar to kitty terminal tabs) instead of a sidebar (assigned to @kommander).

Both solve the same problem (visualizing and navigating multiple subagent sessions) but with different UX approaches:

• Sidebar (feat: add subagents sidebar with clickable navigation and parent keybind #4865, this issue): Vertical space, IDE-style, hierarchical view
• Tab bar (Feature Request: Agent Session Tab Bar Navigation #5826): Horizontal space, terminal-native feel, flat layout

Might be worth coordinating on the preferred direction?
