When a new colony or transport is manufactured the turn begins with a dialog box which doesn't specify which kind of ship is being loaded. On larger maps I may be waging war on one side of my ZOC and colonizing on the other, and the only clue we have now which kind of ship is being loaded is that we can see on which planet the ship was produced. With a dozen or more shipyards I have trouble keeping track of who's making what, so specifying ship type would be helpful.
