Split Screen
Yeaft supports opening multiple conversation panels side by side (up to 3). Great for: talking to two project Claudes simultaneously, A/B-comparing two Copilot outputs, monitoring a long task while chatting with another VP.
Trigger split
Hover any session in the sidebar — a split icon (▥) appears:
- Click it → open this session in a new panel (instead of replacing the current one)
- First click enters split mode (1 panel → 2 panels)
- Up to 3 panels side by side
Panel layout
| Panels | Layout |
|---|---|
| 1 | Full width (default) |
| 2 | 50/50 split |
| 3 | Three equal columns |
Each panel is fully independent: own scroll, own input, own tool-call rendering.
Active panel
Only one panel is the active panel (highlighted border):
- Click anywhere in a panel → make it active
- Clicking a session in the sidebar opens it in the active panel (not a new one)
- To open in a new panel, use the split icon
Close panels
Each panel header has a × close button:
- Closing redistributes width evenly across remaining panels
- Closing the last secondary panel returns you to single-panel mode
Cross-backend split
Different backends can be mixed across panels:
- Panel A: Claude Code Chat (project A)
- Panel B: Copilot session (project B)
- Panel C: Yeaft Code Agent (a discussion group)
State per panel is persisted independently and the split layout survives page refresh.
Relationship to Workbench
- Workbench is an independent right-side tool panel, not a chat panel slot
- The current Web UI hides Workbench while split-screen is active, so Session-scoped tool state cannot drift between panes
- Return to single-panel mode before opening the Workbench capability launcher
Mobile
Mobile doesn't support split — screens are too narrow, single-panel forced. Split layout is preserved but only the active panel renders.
Common patterns
- Comparative review — two Copilot sessions running different models on the same task, compare outputs
- Long-task monitoring — one panel runs a long task (refactor), another panel keeps discussing
- Cross-Agent — one panel connected to Agent X, another to Agent Y
Performance notes
Three panels each running a long task taxes browser CPU/memory noticeably. If your machine feels slow:
- Close unused panels
- Close Workbench (especially Files editor with a large file open)
- Close other browser tabs
