When Tyrian Night is the active theme, the extension can install or repair Island UI. Switching away from the theme restores the stock VS Code shell.
Warning
If Island UI is active, you must run Tyrian Night: Restore Classic UI before uninstalling the extension. Uninstalling Tyrian Night does not remove the custom UI patch.
Warning
Do not click uninstall first. Restore the classic UI, reload VS Code, confirm the patch is gone, and only then uninstall the extension.
The patch surface is intentionally narrow: a single Tyrian stylesheet injected into workbench.html, one CSS asset copied into the workbench directory, and a matching product.json checksum update. Tyrian-owned backups sit next to patched files for reliable rollback, and a small user-level registry tracks managed app roots so Restore Classic UI can clean up completely.
Required uninstall steps:
- Run
Tyrian Night: Restore Classic UI. - Reload VS Code.
- Confirm the custom UI is gone.
- Uninstall the extension.
Commands:
Tyrian Night: Apply Island UI · Repair Island UI · Restore Classic UI · Doctor Island UI
Doctor classifies each managed app root as clean, patched, managed-only, permission-denied, broken-backup, or checksum-mismatch, and offers automatic repair when it finds self-healable state.
Because Island UI patches
workbench.html, VS Code may show "Your installation appears to be corrupt" while it is active. This is expected and does not indicate broken files.

After installing or updating Island UI, VS Code can occasionally restore open editor tabs with a temporary gap between the editor border and the tab row. Close all tabs and reload VS Code once to rebuild the layout.
