Stratos sums it quite nicely,
slewable Maverick... ok, I'll spare Tom Cruise joke here, is I think least possible feature of them all next to CCRP. Ground targets locking for HUD display, simple HARM targetting display a'la F-18 Korea, maybe -if it fit's TK's fun game with nifty planes in it concept.
Thinking of it, what would be the win-win scenario for both sides (if we do have sides here...) would be "just" the ability to give the modders tools to programm some more radar features themselves via ini files, sort of avionics library or scripting. This way those wanting to squish as much as possible from the avionics could have their sandbox to play with
@Icarus999: that was harsh so says me, by God's will Eternal Sun of The East, King of Guadalaqussa, on yer knees minions!
