@kugel- given that the default style is very different between win 7 that @eht16 uses and win 10/11, which are you saying this is not "native" on? And have you any idea of a theme that is more "native"?
@kugel- you just say "not Prof-Gnome" but you don't say what would be better. When you first said above that you don't like Prof-Gnome, you didn't answer @techee's following answers.
So, I assumed it's not that important for you.
In the end, for me personally it doesn't matter much which theme we use, I don't use Windows except for building Geany. But I see that the current theme is probably annoying for anyone.
So, if you have a candidate, it's easy enough to replace the current one.
