I don't know does SCV will have or already have (in SC2) such option (which player can turn on/off) that SCV will repair automatically nearby building or vehicles (like medics in original SC were healing infantry ) if they are in certain moment do nothing. I think that such possibility would be a quiet good and useful. In original SC it was a little bit frustrating for me that I had to order SCV to repair unit by unit by my self. I think that SCV should have option for auto-repair things if player wants to use it.

(sorry for eventually mistakes in my english)

Yeah, SCV currently has the auto-casting Repair ability and you can activate or deactivate auto-casting Repair.
