Ha, thank you. The themeing is not at all my complaint with these tools, but I appreciate the tip! I look forward to seeing what freecad produces, it has a lot of potential but alas, not a lot of funding to make sure the devs can afford to eat.
Last I played around with them the blender cad plugins all use poly modeling, which puts them out of the running for anything more complex than FDM parts. Primarily they exist to either support 3D printing or for simulation/animation of simplified parts. They're... better than nothing, for sure, but unless you need something specifically given by blender you'd be much better served by just using freecad.
