There now follows a basic course on stack management:
- Double click on a unit to select all units of same type from current stack.
- Click on one unit in stack, press 'w' and all wounded units will be selected. These can then be assigned into their own squad
- Click on one unit in stack, press 'e' to select all units in same stack with 2 or more stars of experience.
That should help the army sorting business quite a bit. Assuming of course you don't have too many troops in province for doubleclick to work.
