I hate that there is not a good alternative to InDesign that works on linux.

If only the Affinity suit were to work on linux, even just with wine, I would be alright with the fact that it still is proprietary software. It was somehow able to replace my whole Ph/Ai/Id workflow but it is till keeping me from trying to switch to the penguin.

FreeCAD is getting better but it would really benefit for a big improvement in stability and UX

A decent alternative to Adobe InDesign or Affinity Publisher

I agree but with a caveat: openscad still requires people to understand code. It is still. A whole new skillset that not everyone is going to want to learn.

I agree on freecad! Version 1.0 made it a lot more usable. I moved away from F360 some time ago and now that freecad is more useful it has comfortably replaced 90% of my workflow. It is still a bit clunky, but can get you there.
