Add better control of damaged and promoted units
I find it very frustrating when I move a heavily damaged unit to the back of the attack force, only to have it go right to the front when I move the army. I would like to see an option where the players can automatically keep units at full health at the front of the force, and damaged units to the rear. The same frustration happens with fully promoted units. They keep ending up at the front, and keep my other units from getting promoted. It would be great if I could keep them at the rear as well.
Protect heavily damaged units easier, and help get other units promoted
At times, it may be difficult to tell what is the 'front' and what is the 'rear' of the army.
