Such a pity GTK3 and later aren't intended to be themeable, and the devs make no release-to-release compatibility guarantees for the theme engines. If this only affected Gnome, I wouldn't mind so much. But so many regular non-Gnome apps I use are GTK-based, even if I pick a different DE (which I do), I can't personalise my own user experience in a way that's consistent.
