VonDorkGruber,
with the release of GWX 3.0 I have returned to the SH3-Community. I was looking for an alternative GUI as well and it isn't too easy to find out on your own which mods will fit with GWX 3.0. Anyway, I tried the OLC GUI 1.2.7 yesterday and it seems to work perfectly with GWX 3.0. I must admit I deleted it again nonetheless as the OLC pause screen doesn't allow me to take screenshots nor does it offer the possibility to plot courses etc. while paused. Other than that I experienced no problems or compatibility issues with that GUI. You may find it here:

Today I will try the Periscope TDC 1.2 and the U-Jagd 1.3.1 mods to see what fits best with my preferences, i.e. being able to pause and still using drawing tools on the map and making screenshots.
Gute Jagd!
