Thanks for this mod. Crash dive is cool

I think the 'S'urface sound should be used also when "changin' depth to 0". I have some strange sound inside boat. A long ram, like the diesel sound but slowed down...strange.
Periscope sound - great, torpedo starting - great too."
One more thing - can you replace the native "clear the battlestation" whistle with something neet? It's the loudest sound - and annoying too.
And a question - I've found in the game folder some sounds of crew responses I've never heard in game - 'bout weather, ammunition and others - is it possible to match them with the right activities in game?
