Basically, just let us sort our troops and prisoners. I suggest adding options to sort by their level, formation or troop type (i.e. whether they are cavalry or infantry), whether they can be upgraded (for troops) or recruited (for prisoners).
Shouldn't be too hard to implement, right?

And it should dramatically speed up the process of army management that is so tiresome now.
Also, if you have the time, we could really use some way of telling how many troops of each type (infantry, arch, cav, etc) we have in our army without going into battle and pressing F1. Thanks.
