Inspired by OldHat's requirements I have added new little feature - If you want to edit enemy flights (aircraft numbers, altitudes, morale/skill of pilots) while not reveal their routes/waypoints, you can make a choice now. If you click "Show enemy formations" checkbox, then you will be asked for option.
You can download new executable (v1.0.1) here:
WOFF UE_Mission editor jar Installation: Just place new executable file to your Mission editor folder and when asked if rewrite old file just confirm Yes.
