-**Key Features:**
- **Configure API**: Single `configure()` method for complete app setup
- **View Management**: Automatic view caching, lazy loading, and lifecycle hooks
- **Programmatic APIs**: Full control over AppBar, Main Menu, Secondary Menu, Content Tabs, and Activity Log
- **View Lifecycle Hooks**: `onActivate()`, `onDeactivate()`, and `canDeactivate()` for view components
- **Hash-based Routing**: Automatic URL synchronization with view navigation
- **RxJS Observables**: `viewChanged$` and `viewLifecycle$` for reactive programming

- `setMainMenu()`, `setMainMenuSelection()`, `setMainMenuBadge()` - Control main navigation
- `setMainMenuCollapsed()`, `setMainMenuVisible()` - Control main menu visibility
- `setSecondaryMenu()`, `setSecondaryMenuCollapsed()`, `setSecondaryMenuVisible()` - Control secondary menu
- `setContentTabs()`, `setContentTabsVisible()` - Control view-specific UI
- `activityLog.add()`, `activityLog.addMany()`, `activityLog.clear()` - Manage activity entries
- `setActivityLogVisible()`, `toggleActivityLog()`, `getActivityLogVisible()` - Control activity panel
