A proper implementation of IR/heat signatures would really bring this module up to date. Look at the work on the Hornet's radar, those screenshots. I know, two entirely different things, but it shouldn't be that hard, in comparison to the work on the ground radar.
Again, I would gladly pay for an update of the A-10C module. Perhaps start a thread, with more ideas for such an update, and how much people would be willing to pay for it.
