Panels and the editor tab strip
The editor is 3-column (left / centre / right). This article covers resizing the left / right panels and using the centre tab strip.

Left panel
Resize
Drag the right edge of the left panel. Slima remembers across sessions.
Hide / show
| Action | How |
|---|---|
| Hide left panel | Click the currently-active activity bar icon again / Cmd/Ctrl B |
| Show | Same — it toggles |
Hiding the left panel doesn't hide the activity bar; the panel just collapses.
Switch what's in it
Different activity bar icons map to different panels (file tree / search / AI Coach / Notes…). See Activity bar.
Right panel
Resize
Drag the left edge of the right panel. The AI Coach panel needs some width to be readable — ≥ 320 px recommended.
Hide / show
A ⟨ ⟩ icon in the top-right toggles the right panel — or Cmd/Ctrl . on platforms that support it.
Centre tab strip
The tab strip at the top of the editor holds multiple open files.
Actions
| Action | How |
|---|---|
| New tab | Click any file in the tree (opens as a new tab) |
| Switch to existing tab | Click the tab |
| Close | × on the right of the tab |
| New blank chapter tab | File tree "Add Content" → Chapter |
Tab order
Open order = display order. The current UI doesn't support drag-reordering tabs (you can reorder files in the tree itself).
Hide both = Zen-like focus
Hide left + right panels + F11 full screen → very close to a clean writing canvas.
