Here's a neat maneuver trick that I like to utilize in a real life casual game. If you place the template on the center of the left or right of the base and line it up in the center of the same side at the final position, you get an easy maneuver without having to mark ships.
Bear in mind, it only works with turn maneuvers and the final position is approximate, but in a casual game it can really speed up the activation phase.
