Tabs, panes & split layouts
Drag-to-split panes, tab groups, and pinned boundaries.
Orca's pane system is designed for watching multiple agents work without losing context. Tabs group into panes; panes split into layouts.

Tabs
Each tab holds one thing: a terminal, an editor buffer, a browser, a diff, a PR. Tabs live inside a tab group.
- Drag a tab up-down within a group to reorder.
- Drag a tab onto another group to move it.
- An active-tab color bar marks which pane is focused.
Split panes
Drag a tab to the edge of a pane to create a split:
- Right edge — splits left/right (horizontal split).
- Bottom edge — splits top/bottom (vertical split).
Splits nest. You can have an agent terminal on the left, a diff view on the top-right, and a browser tab on the bottom-right — all at once.

Pinned boundaries
Pane boundaries stay where you put them. Resizing the window doesn't shuffle your layout; boundary positions are saved per worktree.
Tab groups across worktrees
Each worktree owns its own tab layout. Switching worktrees swaps the entire pane tree — your browser tab, terminal, and diff reappear exactly as you left them.
