Well, I understand why one wants to use a native GUI toolkit (Cocoa) instead of a more generic but cross platform one (for instance Qt). GUIs just feel smoother

Well, I understand why one wants to use a native GUI toolkit (Cocoa) instead of a more generic but cross platform one (for instance Qt). GUIs just feel smoother. This has always been a thing for Mac OS applications -- but interestingly never so much for Windows applications, because look and feel was always prioritized in the designer-addicted Mac world. I like that -- the Mac UIs always used to feel high quality and polished. Nevertheless I'm a 15yrs Linux user and pay the price of the Gtk/Qt "uglinesss" for my freedom (it's not so ugly any more :D ).
