Of course, I support what is already working, but in my opinion, that is not it. It would still like more freedom for user settings.
In Settings -> Themes, add additional sub-tabs to set, for example, colors in the mixer, playlist, browser, channel rack, fonts and buttons separately. Background and foreground in groups of control elements or even framing.
So far, there are not many nice offers of skins from users. Just my opinion.
