This commit refines the visual hierarchy and fixes layout issues in the
settings dialog:
1. Add visual separators to dialog sections:
- Add bottom border and background to DialogHeader
- Both header and footer now have consistent border + bg-muted/20 styling
- Creates clear three-section layout: header | content | footer
2. Fix footer overflow issue:
- Remove min-h-[480px] from content area that conflicted with max-h-[90vh]
- Keep min-h-[400px] on TabsContent to prevent height jumps
- Add flex-shrink-0 to header and footer to ensure they stay visible
- Content area uses flex-1 to fill remaining space naturally
3. Improve spacing:
- Add pb-4 to content area for breathing room above footer
- Add pb-4 to DialogHeader for consistent spacing below title
- Ensure proper padding hierarchy across all dialog sections
Layout calculation (small screens, 90vh ≈ 540px):
- Header: ~70px (fixed)
- Content: 400px minimum, scrollable (flexible)
- Footer: ~70px (fixed)
- Total: ≤ 540px, footer always visible ✓
Files modified:
- src/components/ui/dialog.tsx (DialogHeader, DialogFooter styling)
- src/components/settings/SettingsDialog.tsx (content area height constraint)
Fixed multiple layout issues in the settings dialog:
1. Dialog structure: Changed from grid to flexbox layout
- Removed global padding from DialogContent
- Added individual padding to DialogHeader (px-6 pt-6) and DialogFooter (px-6 pb-6 pt-4)
- Added max-h-[90vh] constraint to prevent dialog from exceeding viewport
2. Content area improvements:
- Replaced max-h-[70vh] with flex-1 for better space utilization
- Set min-h-[480px] on content wrapper to maintain consistent dialog height
- Applied min-h-[400px] to all TabsContent components to prevent height jumps
3. Scrollbar optimization:
- Changed overflow-y-auto to overflow-y-scroll to force scrollbar gutter
- Eliminates horizontal shift when switching between tabs with different content heights
- Consistent with main app layout approach (App.tsx)
4. Footer enhancement:
- Added border-t and bg-muted/20 for visual separation
- Fixed footer overlapping content in advanced tab
Result: Settings dialog now displays all content properly without requiring
fullscreen, maintains consistent height across tabs, and eliminates layout shift
when switching tabs.
Fix inconsistent modal overlays by migrating all custom implementations
to the unified shadcn/ui Dialog component with proper z-index layering.
Changes:
- Update Dialog component to support three z-index levels:
- base (z-40): First-level dialogs
- nested (z-50): Nested dialogs
- alert (z-[60]): Alert/confirmation dialogs (using Tailwind arbitrary value)
- Refactor all custom modal implementations to use Dialog:
- EndpointSpeedTest: API endpoint speed testing panel
- ClaudeConfigEditor: Claude common config editor
- CodexQuickWizardModal: Codex quick setup wizard
- CodexCommonConfigModal: Codex common config editor
- SettingsDialog: Restart confirmation prompt
- Remove custom backdrop implementations and manual z-index
- Leverage Radix UI Portal for automatic DOM order management
- Ensure consistent overlay behavior and keyboard interactions
This eliminates the "background residue" issue where overlays from
different layers would conflict, providing a unified and professional
user experience across all modal interactions.
Introduce `closeAfterSave` callback to distinguish between save-and-close and cancel-and-close scenarios. Previously, saving settings would trigger `resetSettings()`, causing language changes to revert and requiring users to save twice for the change to take effect.
Changes:
- Add `closeAfterSave()`: close dialog without resetting settings after successful save
- Keep `closeDialog()`: reset settings when canceling or directly closing dialog
- Update save flow to use `closeAfterSave()` in `handleSaveClick`, `handleRestartLater`, and `handleRestartNow`
