Operation Monsun Installed, have a few questions.

So I got it finally installed and I have to say Im very impressed, other than the GUI (Again I liked SH3s better) I really like the look and feel of the game! It looks unbelieveable and it even runs smoother than Sh3 does!! Thats a plus, on top of that I think the water and such looks so much more real than Sh3. But I have a few questions.

While Im getting used to the crew management, if someone could is there a guide explaining how to work it?? As well as damage control.

Secondly, Do ships in OM sink the same way as they do in GWX?? (By flooding or structural integrity?) I havent played SH4 enough to find out if they do.

third, when in the periscope view, I couldnt help but notice there was no Gyroangle setting to tell me after I had ID'd and done the calculations for a target where to set my periscope. Whered it go??

And finally, are there any other mods you all reccomend to run with OM?? I currently have OM and Omegu thats it.
Thanks guys!!
