This is my XFCE setup.
I like clean layouts and dark themes. XFCE is extremely customizable and snappy and I always come back to it.
Fonts: Cantarell Regular, 11
Icon pack: Tela
Wallpaper Source: https://wikiway.com/lithuania/palanga/photo/
Window borders: Mojave-dark
The result is a minimal desktop, easy on the eyes.
