Feature request: optional UI tooltips / learning mode for non-obvious interactions (split view, rewind, pickers)
Is your feature request related to a problem?
The desktop app (and CLI) rely heavily on non-discoverable interactions: split view via Ctrl+click in the session sidebar, closing a pane with Ctrl+\, /rewind checkpoint selection and its restore options, double-Esc behavior differing based on whether the input has text. As a non-developer user, I needed several rounds of Q&A with Claude just to split two sessions side by side and pick a rewind point — each answer was one sentence, but nothing in the UI surfaces it.
Describe the solution you'd like
An optional "tooltips / learning mode" setting (off by default) that overlays short hints on interactive elements:
- Session sidebar: "Ctrl+click to open side by side"
- Split panes: "Click a pane to focus it; sidebar clicks replace the focused pane; Ctrl+\ closes"
- Rewind menu: one-line explanation of each restore option (conversation / code / both / summarize)
- First-run pickers and other interactive menus: what the keys do
Veterans keep the current clean UI; new users get in-place learning instead of trial and error or asking the model about the harness UI.
Describe alternatives you've considered
Asking Claude in-session works but burns turns on UI mechanics; docs cover it but require leaving the app and knowing what to search for.
