I use FreeCAD for woodworking, and...yeah. It works, it has its limitations, and I figured I know some Python, maybe I can code up some tools for woodworking specific tasks that would speed the process up.

Almost none of FreeCAD is documented and what documentation exists is wrong. You can't learn how to contribute to FreeCAD, you have to be born knowing how. It makes no goddamn sense. "You know the chamfer and fillet tools in the Part Design workbench? I want one that makes Rabbets" is a bigger R&D problem than the Manhattan Project.

My understanding is that there are long-term developers who have left, and new blood is starting to appear, which is why the next version is going to have a lot of improvements to the sketcher among other things.
