That looks even cooler IMO! I am using POP OS 20.10, apparently Gnome edition using shell version 3.38, wish there was somebody who could do icons for it. The default POP OS icons are not the best, and most certainly could be improved.
As far as the theme package, I am currently using Aravisian's Azenis theme, but it doesn't include the icons for gnome. And let me tell you something I had to painfully learn, don't try to switch to icons made for XFCE, in gnome.
Cause as soon as you do, it will break your system, totally hijack it, keeping all functionality away from you. And its so bad, that you have to boot into recovery mode, open Nautilus as root, and then remove the icons folder from there.
So ya, word of advice people, if you install an icons pack, make absolutely sure that the icons your installing, are for Gnome, before you activate it via Tweak tool lol.
