It would be nice if there was a way in game to speed up the movement/animation of a given ship. I find I spend a lot of time watching ships moving for trivial actions (as I probably spend too much time manually controlling too many ships).
I don't necessarily want a global civ-like instant move option. But in some games you can double click to do a fast move, or hold shift to speed up a unit's movement - something like that would be ideal. So when my 20+ move constructor is putzing along I can give it a swift kick and move on to the next constructor a bit quicker.
