Issues I noticed/suggestions:
Already deployed units on the map cannot be viewed in the menu unless all units have been deployed which can be annoying.
Having a sort by type in the menu for your units on the map would be handy, not just in the buy menu.
Would be nice if there was a unit deselect button other than clicking on a out of range hex or re- clicking on the unit which can be a problem for planes who are already positioned on top of an enemy, which causes an unwanted attack. Hope this makes sense.
