1 - is a good idea, added to the list
2 - is surprisingly a lot of work and we decided not to include it for now - too much work (like 2 weeks)
3 - this is in already. Every time u create a new army, or have an army transfer units window open - click on the Army name, and type in a new name
4 - perhaps - but really we didn`t have any complaints about players being unable to locate their armies, maybe we just missed these.
