One thing I noticed here is that you're only able to name a battleship, not a destroyer, not a cruiser and not a submarine. However, all of these units had names during WW2 and in my opinion should also have them in the game. Not only because it's more historically accurate, but also because it helps finding units and remembering where they are. It's just a suggestion, but I would really like the option to be in the game.
