It is nice to have a ship movement command "Go to Colony" which I don't see in DA. Sure, you can set up a rally point on each colony and do it that way, but that's considerable extra key strokes. An advantage of this command is that the ships go into orbit and thus if they are warships help defend the colony while they are waiting to be used elsewhere, or if they are not warships they are more safe from casual attacks by roving enemy warships.
