Case study

Keymarks: reconstructing Powermarks 3.5 bookmarks and workflows

Keymarks rebuilds Powermarks 3.5's keyword-based bookmark workflow as a Windows Tauri app with SQLite search and a browser extension. Its author used REA with Ghidra to recover the undocumented pm35.htm record layout from pm.exe and implemented import and export for that format. A separate feature inventory draws on the original manual, changelog, settings and executable strings.
