I believe it's been mentioned before, but I'd like to reiterate that we need some sort of "dimiss" functionality usable from the window used to examine a unit. All too often you will end up with straggler units that are too weak, left way behind your commanders, that aren't worth going to reclaim (even if just for cannon-fodder). So these units just sit all over the place consuming gold and/or food while you pray that something will come along and kill them for you.
PLEASE?
