I'm amazed at the level of effort you're putting into this... and very grateful... especially considering you're doing all of this out of your desire to better the community.
One thing I noticed just now because I've been playing around with the more advanced sub missions is that the GUI doesn't have any support, at least as far as I can tell, for advanced, programmable torpedos. This may have been covered before, and that may be by intention or I may just not know how to get to it, but I just thought I'd bring it to attention.
Thanks again for the great mod,
Greg
