Hello Pokara and this looks like a nice addon for GreyWolves.
However I am not playing with the GreyWolves add on at the moment

. But I was wondering if you or someone else would be kind enough to inform me as to what mods you used to get the bottom of the game screen to look like the first three images you posted?
Also if its not too much more bother would you mind telling me what mods you used to get the periscope screen to look like the one in your screenshots? Is it also possible just to mod it so that it has the depth guage (that looks like a barbers pole) and everything to the right of this screen shot?
Thanks..
