DivingDuck,
now that you have been able to link animations like food and lights to depth and time of the submarine, would you consider making the dive planes guys invisible while the boat is surfaced? It always annoys me to see them there while the boat is cruising on the surface, something that in real life never happened. It doesn't matter if the icons are still in the F7 screen, as the game needs the crew to be there in order for the sub to move and steer, but it would be cool if they would be at least invisible while surfaced.
In real life, the watch crew is the one that would man all plane stations and dive controls after getting down from the bridge.
