[Suggestion]List of all units and toggling between them
EDIT: Removed the bug report (why can't I delete posts here?) due me missing a simple thing in the game. Leaving the suggestion intact.
Suggestion:
It would be cool if all units did line up as circles on the bottom left of the menu bar, and get stacked closer and closer depending on how many you have. Inactive/fortified(?) units could be half sunken down into the menu bar, and the active unit should make more room for itself to be fully displayed. There should then be a button to toggle between all units.
