Not sure if this has been addressed, but especially after coalition flags under national flags were removed from the map view, it is somewhat cumbersome to determine which nations fall under which coalition. I am aware that you can select provinces to see the flag, but I have a possible idea.
Something like the relation map mode, there should be a map mode that colors each coalition's territory differently.
