## Summary
I've implemented the fix for showing the left sidebar when entering `WorkspacesLayout.tsx` when no changes/preview/logs panel is open:
**Changes made to `vibe-kanban/frontend/src/components/ui-new/containers/WorkspacesLayout.tsx`:**
1. Added `setSidebarVisible` to the destructured values from `useLayoutStore()` (line 161)
2. Added a new `useEffect` (lines 333-338) that shows the sidebar whenever no panel is open:
```typescript
useEffect(() => {
if (!isChangesMode && !isLogsMode && !isPreviewMode) {
setSidebarVisible(true);
}
}, [isChangesMode, isLogsMode, isPreviewMode, setSidebarVisible]);
```
This ensures that when the component mounts or when all panels are closed, the sidebar will automatically become visible.
