Show HN: DiffCAD, a FreeCAD workbench to review model changes like code

I'd like to share a new workbench I've been working on called DiffCAD. Coming from a software engineering background, not having the ability to properly diff my CAD model changes was driving me crazy. This project scratches my own itch, and maybe someone elses', too!

I'm open to feedback, ideas, and contributions. Cheers!
