## Key Features

### ConfigValidator
- Comprehensive schema definition
- Type validation (str, int, bool, list, Path)
- Value constraints (min/max, allowed values, length)
- Detailed error messages
- Reusable for all configuration validation

### ConfigProfile
- Save configurations as named profiles
- Profile storage: ~/.webdrop-bridge/profiles/
- JSON serialization with validation
- List/load/delete profile operations
- Error handling for invalid names and I/O failures

### ConfigExporter
- Export current configuration to JSON file
- Import and validate JSON configurations
- Handles file I/O errors
- All imports validated before return

### SettingsDialog
- Professional Qt QDialog with tabbed interface
- Load config on initialization
- Save modifications as profiles or export
- Import configurations from files
- All settings integrated with validation
- User-friendly error dialogs

## Code Quality

### Validation
- All validation centralized in ConfigValidator
- Schema-driven approach enables consistency
- Detailed error messages guide users
- Type hints throughout

### Testing
- 43 comprehensive unit tests (100% passing)
- 87% coverage on config_manager
- 75% coverage on settings_dialog
- Tests cover normal operations and error conditions

### Documentation
- Module docstrings for all classes
- Method docstrings with Args/Returns/Raises
- Schema definition documented in code
- Example usage in tests

## Integration Points

### With MainWindow
- Settings menu item can launch SettingsDialog
- Dialog returns validated configuration dict
- Changes can be applied on OK

### With Configuration System
- ConfigValidator used to ensure all configs valid
- ConfigProfile integrates with ~/.webdrop-bridge/
- Export/import uses standard JSON format

### With Logging
- Log level changes apply through SettingsDialog
- Profiles can include different logging configs

## Phase 4.3 Completion Summary

✅ All 4 Deliverables Implemented:
1. UI Settings Dialog - SettingsDialog with 5 organized tabs
2. Validation Schema - ConfigValidator with comprehensive checks
