[BUG] Web UI: File tree toggle hidden by desktop() gate in settings, and panel not open by default #34223
Closed as not planned
Description
Description
When using OpenCode via opencode web (browser), the file tree cannot be enabled because:
- The "Show file tree" toggle is hidden — it's inside the
AdvancedSectioninsettings-general.tsx, which is gated behind<Show when={desktop()}>. Sincedesktop()checksplatform.platform === "desktop", it's alwaysfalsein the browser/web context, hiding the toggle entirely. layout.fileTree.openeddefaults tofalse— even when visibility is forced on (e.g. production where!newLayoutDesigns()istrue), the panel haswidth: 0pxbecauseopenedisfalse.
The keyboard shortcut Ctrl+\ / Cmd+\ does toggle the tree open, but there is no UI affordance for web users to discover this.
Expected Behavior
- Web users should be able to find and toggle the "Show file tree" setting in Settings → General
- The file tree should be discoverable without needing to know the
Ctrl+\keyboard shortcut

Wanted to note also that the issues described are also affecting the "Toggle File Tree" on the new layout in Desktop.
Settings -> General -> Advanced -> File Tree(as stated by OP that it is visible in Desktop) is defaulted tofalse, so unless the user manually knows to go to that advanced setting to flip it totrue, the File Tree can't be opened. In the old layout thevisible()short-circuits totrueregardless of the preference:github-actions commentedon Aug 29, 2026
