The first option for a CAG is "auto-invert activation group icon color". My guess is that this would highlight the CAG in the BTT Sidebar when the conditions are met. But it doesn't seem to do this. So what does it do?
it inverts the colors of the groups icon when necessary, however this only works for black and white icons with transparent backgrounds (because it used the image as a mask in this case)
It’s only so the icons look nice in the sidebar
