Editor addon that adds a Bookmarks header to the asset browser and shows virtual folders like Models and Materials plus user-defined locations. Users can create and edit custom locations with asset type filters and include or exclude paths, which are stored per project and rendered as injected tree nodes. It scans for a Hammer asset browser type at runtime to register itself when present.
Unit tests for the Asset Browser Bookmarks library. It boots a Sandbox.TestAppSystem for the test session, creates a Scene and a GameObject, then asserts the scene directory reports one object.
