Yes indeed ~/.local/share/themes
So here is UBudgie 18.04 :
Chromium, LOcalc, Thunderbird
Chromium, LOcalc, Thunderbird with Qogir-dark, begin the problems ( thunderbird )
Firefox, Sayonara ( Qt ) with Qogir
Firefox, Sayonara ( Qt ) with Qogir-dark
back button in FF ? Sayonara ?
Firefox, Synaptic with Qogir-light
Synaptic looks like … Sayonara, not themed ?
Oh and what’s that white bar at right of Budgie-Menu ?
Pixelsaver with Qogir-light ( but same problem with any Qogir shade )
This problem with pixelsaver applet is present with almost any theme ( except where it has been fixed : pocillo, adapta …others ? )
Pixelsaver should have the same background as panel, and not the background of windows theme. I think it means actually no background at all.
I did not post again a picture of Nautilus but for left button lovers, the solus logo at left might be counter intuitive ( is it supposed to have any effect when clicked ? )
Anyway, all over, it looks nice ( but quite close to Adapta )
I know these are the Solus colors but any chance to have this theme + its matching folder icons ( which are ? ) with other accent colors instead of blue ( green mint or mate, orange ubuntu, you get the idea… ) ?
Or - for that specific default / distro theme - an option in budgie settings to modify that accent color ( and folder color accordingly ) ?
