It would be nice to be able to lock units. A locked unit would *not* get selected when you drag a selection box over them, whereas unlocked (normal) units would.
Often I leave units in strategic positions but it deteriorates quickly once a battle begins and they get sucked into battle by accident.
Scenarios where it would be helpful:
* leave scouts in good positions
* selens never move
* a few tanks left back at base just in case
* a t2 flak set to assist commander and then locked (it will continue to assist but will be very hard for you to give it a new order by mistake)
It would be cool if unlocked units weren't selected by other methods as well, like ctrl-A selecting all air, would only select unlocked air units.
Directly clicking on a locked unit would be the only way to select a locked unit. Then you could unlock it, or just give it orders as usual.
There would be some sort of visual indicator that a unit is locked.
There would be a hotkey to toggle lock.
There would be a hotkey to unlock everything on the map. This is kind of a panic button
Usually this is when Domino says he will have it built in 15 mins and then Zock says it's already existed for years.
