Description

When the sidebar style is set to 'Hidden' (0px width when collapsed), the sidebar toggle button in the footer becomes inaccessible — it disappears completely with the sidebar column. The only way to restore the sidebar is via the ⌘B keyboard shortcut.

This raises a question: Is this the intended behavior?

It seems problematic because:

• Users who prefer 'Hidden' style lose all visual way to restore the sidebar
• If a user sets sidebar to 'Hidden' but later wants to change it back, they cannot use the UI, only the keyboard shortcut works

How to Reproduce

1. Go to Settings → Interface → App Layout and select 'Tab Focused'
2. Go to Settings → Interface → Sidebar → When Collapsed and select 'Hidden'
3. Collapse the sidebar (⌘B or toggle button)
4. The sidebar column disappears entirely (0px width)
5. The toggle button in the footer is gone — no visual way to expand

Question

Should the toggle button remain accessible even when sidebar style is 'Hidden'? If so, it might make sense to either:

• Keep the icon rail (44px) regardless of style setting, or
• Place the toggle button outside the sidebar column (e.g., in the title bar)

If 'Hidden' is intentionally meant to hide everything including the button, then this is by design and the issue can be closed.
