I have just noticed that if I unassigned myself, my ship would keep going. Since I don't own a captial ship though, I don't know whether this will work on one, but if you set coordinates for a capital ship, then unassign yourself pilot, and then enter a docked ship or vehicle, will the ship keep on moving?
Oh, that's implimented already? (Just read rules on it.) I coulda sworn I just saw a post in the suggestions forum a week or so ago suggesting it. Anyways, thanks.
