On that subject let's say I have an Escort the Bombers mission. If I was playing a scout campaign can I modify waypoints of all flights involved, i.e., the escorted bomber flight? Sometimes their waypoint selection (how they fly their mission) leaves me shaking my head.
With this mission editor it is possible to modify ALL flights and all parametres. But, to do not spoil the immersion, enemy flights are hidden by default, but you can enable them for view/editing by toggle button.
