Wanted to say thank you for taking the extra time to make your GUI stock-compatible.
I just got the game recently and have been applying the "softly, softly" approach I've seen recommended many times with regard to modding.
However, after playing through the naval academy, the data acquisition system (i.e. the notepad) had to go, so I came hunting for a new system and found your GUI. Got all the targets in the naval academy torpedo mission in the first attempt using your GUI.
So thank you, to you, Hitman and joegrundman.
Mr.Moe.
