An editor tool that audits a project's assets and helps you navigate references. It scans files for quoted asset paths, validates and groups findings, detects dependency cycles, and shows who uses or is used by a selected asset. It has dockable windows, focuses assets in the Asset Browser, and exports Markdown, text, or JSON reports to disk.
