Read the boundary with the feature
- The public product source describes vertical tree tabs and modal navigation.
- Gjoa also ships a horizontal tab surface — see Horizontal tabs — and switching between them is a live setting, not a rebuild.
- The screenshot on this site is the public Gjoa new-tab screenshot, not a reconstructed mockup.
