When I tried KiCAD several years ago, I was drawn in by the extensive feature list only to find that it suffered from the same issues as Blender, another mayor open source project, it was mainly feature driven, and the UX was horrible. Enough at least for me as a hobbyist PCB layout software user to leave it be for a few years.

I'm kind of derailing here, but I strongly disagree about the Blender UX being horrible. After getting used to it, I find it one of the most usable pro tools. The command-based approach is IMO far superior than the usual approach of having tools and a toolbar you must switch. The windowing system is amazing and everything being scriptable is incredibly powerful.

I consider it somewhat similar to vim or CLI programs in general in that regard... It violates all conventions you are used to, but internally it is very consistent and well made.

I have heard all EDA UX's are horrible.
