I start this discussion just to ask about some details and I don't think this should be sent into comment to bother everybody

I noticed that there are command_handler_callback(s) to detect orders other than attacks to release units from the auto attack mode, it seems that the "move a bunch of unit with there relative position kept" order by drag the mouse while holding ALT key and rotate them with CTRL key, this operation does not count as a move order.
I wonder whether this kind of order can be added, or CA didn't provide an event to be listened to.
