When I am plotting my moves the game displays light blue movement lines to show me where leaders have been ordered to move, and the path they will take. Once there are several of these on the map it can be hard to pick out the one I want. Could you have the movement line display in RED for the currently selected leader?
In the notes area at bottom battle resolutions show up in RED. Can you have reinforcements show up in BLUE?
(edit to add: By the way, I am having a lot of fun with your game. I may have to get the ACW game as well. Good stuff!)
