- [x] 1.4 Add getter methods for checking column visibility
- [x] 1.5 Add action methods for toggling column visibility

## 2. Create Sidebar Column Switch Component

- [x] 2.3 Integrate with `useColumnVisibilityStore`
- [x] 2.4 Style component for sidebar context (compact, collapsible)

## 3. Integrate Component into Sidebar

## 5. Testing and Verification

- [ ] 5.1 Test column toggle from Sidebar updates Shot table
- [ ] 5.2 Test column toggle from Shot page updates Sidebar control

- [ ] 5.4 Test default visibility for new users
- [ ] 5.5 Test behavior when sidebar is collapsed/expanded

## 6. Edge Cases

- [ ] 6.1 Handle case when no project is selected
- [ ] 6.2 Handle case when task types list is empty
- [ ] 6.3 Test responsiveness on mobile (sidebar behavior)
