# Documentation: UISettingsViewModel

## 1. Purpose

`UISettingsViewModel` is a Prism-based view model within the `UISettings` namespace that serves as the presentation logic handler for UI settings configuration. It implements `IUISettingsViewModel` and coordinates between its associated view (`IUISettingsView`) and the broader application infrastructure through Prism's event aggregation and region management. The class provides notification and confirmation dialog capabilities, busy state management, and exposes UI configuration flags for menu and navigation inclusion.
