Fixed, thanks. I report you some more things in case you like them:
-Active tab is darker than the ones in background, it can be confussing, usually the active one is lighter than the others.
-The toast or notification popup has the colours from your dark theme. That's why variables are in help when creating new skins and are very easy to add. Just search that colour value and change it for a name: I use ground, ground+1, ground+2, ground-1, ground-2, selected, selected-1 for differencing layers like a topographic view.
