What makes Linux appealing to me is the extent of customizability, but I didn’t find many answers when looking up with desktop environment is them most customizable. Some say KDE is most customizable than say, Gnome, but doesn’t Gnome support CSS customization while KDE doesn’t?
Btw, every.single.one of those one-icon plugins, like battery-indicator or pulseaudio-plugin, should at least have a icon-size chooser in their settings. Always needs debugger and some custom CSS.
