I said I'd have a request - here it is: these communication tubes are empty from inside, but not from outside. As they are just over the map, every time I approach map table this view strikes me and kills immersion:
EDIT: I also think the most important next step in interior development is making
every dial behave - move, indicate just anything, even random values. It's very disappointing to see most of the dials just staying in the same position all the time (usually in the middle of scales).
Of course it would be marvellous to have working main dials in every compartment or at least every major station (speed, compass, depth, RPMs).
