I know a thing or two about UI/UX, but tbh it feels very weird to me to butt in somewhere and tell people what to do. Because unfortunately, while I probably could design a good UI, I have no experience in implementing UIs.
I can deal with C++ so I thought I might as well learn Qt, but I couldn't even get Qt Creator or KDevelop to run properly on my distro and didn't find the time to get into it since.
This stuff sadly not that trivial which is probably why you don't find too many people who can do it.
