There would be very nice to have a navigation aids, for example:
1. Click on a location on the map and get the distance and heading in flight, also get the altitude on this point on the map.
2. Click and drag - get the distance and heading between two points.
3. E6B calculator - given distance and speed get time and distance and time get required speed
It would be very helpful especially for bombers that need to plan their attack direction.
Also it would allow it easier to define points were an escort meets bombers etc.
