A little thing, but can be a bit annoying:
In the Upgrades section, it would be nice to know how many +++-tier units I have (as I don't want to bother upgrading to +++ if I've already got a full set), so I don't have to go back to the army composition screen just to see that information.
Hmmm actually this might be an easy fix, and I agree it would be ideal. It has been a long time since I've touched the upgrades code but as I am planning to add mass-upgrades soon anyway this seems like something to include in that pile as well.
this will be in the next upload
