hey, hey. I was thinking something similar, and also that the "helicopters" mod -- which adds one helicopter -- would benefit from some of your realism features. It was convenient that jumping out while moving just had it cruise to a halt landed right on deep water a short ways from the shore, but it didn't feel "right."
the reason I mention it right here is that helicopters come with a pair of gauges that show remaining fuel, airspeed, altitude, and engine RPM. (The last is more decorative than useful, but y'know, a nice, and "adds the feel of real" decoration.)
Also also, one or the other mod will move the helicopter behind the aircraft tech, if it is present, so there is already some basis for cooperation.
Plus, if multiple amazing mod authors work together on it, the gaugues might end up, eg, using the new GUI capabilities sooner and being much more "designed for this" like in the game. without me needing to do the work, #lazy :)
