Enemies with treasure should have a yellow or orange cursor; enemies robbed until they have no treasure a brown cursor; Saruman (once you see his Keys) a purple cursor. Pickpocket should put a red cursor on robbed enemies if you don't have Eye for Detail or haven't seen if that enemy has treasure. Sadly, I don't know how to make cursors.
