linux and the DEs dont make it easy to write apps for, this is a compositor/window manager/de issue to solve.
Want to write an for gnome? Javascript or c++. Enjoy libadwaita. Want to write for kde? C++ only. Dont want to write js and you only know kotlin/swift/java/objc? Tough fucking shit, get fucked. Want to write rust? Not supported by kde or gnome ootb, the learning resources are bare etc. Oh and for kde you have to learn QT as well have fun:)
Itd be cool if rust was the baseline standard for writing apps and was fully supported by the major DEs. I honestly cannot be bothered to learn C++ just to make a tiny app for my desktop, I will never use it again in my life because it is dying.
