How about an updated game map?

Would it not be possible to add the names of the different bodies of water throughout the world onto the game's navigation map with a light gray or blueish color? This may help folks to be able to recognize different grid locations without having to resort to looking all the time. I am not a geography guru and I admit I don't know the names and locations of all the different bodies of water in the world just off the top of my head, so it could also be used as a geography tool for us less edumicated
