The ability to do what was called "riding the vents"= faster dive
The decks awash idea with people on the bridge IF it reduces you're radar signature and makes it harder for the AI to spot you visually (the other reason for running this way).
Maybe I've missed this somewhere but the ability to order left or right rudder in 5 degree increments via keyboard like the old silent service 2 had (tried to find a cmd like this to activate, maybe I missed it?)
