Okay, so I know this is not really very important, and I can only really see one situation where it could be useful, but still.
Would it be possible to allow for manual removal of ACU upgrades? At present, the only way to 'uninstall' an ACU upgrade is to replace it with another one. This is inconvenient in one particular situation:
Playing as UEF, I had the dual shoulder drone upgrades. (It was on the coop mission Prothyon-16, so that was the only back upgrade I had at the time) However, those drones kept getting killed by Interceptors and wasting resources on the rebuild. Lacking any other upgrades unlocked in that slot, I couldn't replace the drones.
Is it possible to add some function to remove ACU upgrades without replacing them?
