Just a note regarding Adapta theme and Papirus icons : those are very complete, under almost any distribution, why not use them by default instead of reinventing the wheel ?
Adapta needs to revive, in quest of a new maintainer though. Same for Arc but it seems on good way.
( wish there was in Adapta an easy way to change the accent color - not fond of blue-green - and have the folders colored accordingly ).
Adapta is the only external theme where pixel-saver applet is correctly themed. Even Pocillo fails at it ( the X button is wrong ).
Very offtopic but is that Panel, on the far left side? You use that as Panel + Dock replacement, pinning favourite and running apps?
Didn’t know that was possible. May I ask how?
