How do you manage space tugs? They don't automatically follow the mobile repair station, and they're grouped by their percentage type rather than a 'base' type, where double-clicking on one would select them all. Also, how do you tell them to automatically tug any damaged ships in the system? FRD mode?
And the annoying problem would be that when they tug the ship in for repair, after the ship is repaired to 100% life, whatever command they were performing before is cancelled. This can get really annoying when you have 5 repair stations with 1000 ships and you constantly have to tell your repaired ships to go back into combat, or else they'll just sit there and do nothing.
