I know it's a theme that's been out there for a while but I got tired of the green folders and same icons. This really surprised me. It's just nice, modern and doesn't appear to break (as yet). I downloaded it off of mate look. https://www.mate-look.org/. The theme is called: Qogir-win dark
Yes, Qogir is very nice. I especially like the Qogir icons. Very neat.
