New Hotkey Needed: Select damaged units

[Jaybe]

You can also select the group of units and Ctrl-Click to omit units from your selection. Either on the map or the selection display.

I think 2 drag select filters (very dammaged units and all dammaged units) would work wonders.

Auto garrision work every while for planes. When badly damage, it returns to base for repair.

In a game call DARK "Region" (not to sure), planes can be set to roam and attack. When damage to certain %, it returned to base for repair before returning to duty. Players can set the damage %. This tactical is very good, while the planes are roaming, they spot incoming armys and attack them.

The game is Dark Reign and had behavior and "retreat to repair" adjusments for all units.
Also it had a feature named Seek % Destroy, where units autoexplore the map end engage any enemy they found. Very usefull in the end of the game. However, RoN dosen't need this feature. You don't have to destroy all enemy units to win, not even with the conquer seting.
