Optimized POI Display with Common Tree View

Replaced custom POI list with Unreal’s Common Tree View for improved performance and scalability. Supports hierarchical organization, built-in selection handling, and native list virtualization for faster rendering of large POI sets. Key Advantages:
Common UI Menu Hierarchy & Input Routing
Initial implementation explored using Unreal’s Common UI framework for layered menu navigation and input handling across widgets. The feature was put on hold due to AVE II’s single-platform focus and lack of clear documentation, which would hinder usability for developers. The current UI framework already offers adequate customization and can be easily expanded further.
