Allow More Target Area for Sidebar
Reviewing dolphin in 15.90.90 it seems that the sidebar targets on Dolphin need to be enlarged. It seems to require a bit extra precision from the user to click the right folders in this area. I am not sure if this area of the application follows a specific metric but allowing more pixels to surround the target area should make it more comfortable for the user to click. It will also make it much more evident to know what has been selected.
I think it would be good if the spacing in the margins was increased by 30-50%
