Last week I added to my dolphin toolbar the "Show Hidden Files" button so it was always shown, my only issue was that it was a really long because of its text.
"But wait!" I thought, "This is not windows, I'm sure I can change it!". Lo and behold, my button now says "Hidden" and it's as short as I want it, just by editing the normal settings, no mods required.
Yeah, between KDE and Cinnamon I can focus on my work and have the desktop environment gently fade into the background. Though some get a similar feeling using stuff like i3, sway or Niri.
