More subtle focus indicator
The current green 1px border for the focused item is excessively opinionated (I would say it's awful but it's a matter of opinion :) ). Then one should resort to hacks like
Transparent Dolphin View in
kvantummanager in order to avoid looking at a useless green rectangle all the time while using
dolphin. Why not change it to a subtly (but not sooo subtly) brighter version of the theme base color?
In general the green color is beautiful, of course, it's manjaro flag color. It's just that 1px rectangle. I would change it by myself if it weren't so difficult (for me) as changing a svg file.
