Nice-to-have enhancement to BaseCamp:
In addition to the present four routing options (automotive, bicycling, hiking and motorcycling), add "great circle". This would allow the creation of flight routes. Obviously, this would not (could not) be used for actual navigation during a flight, but would serve to display a record of approximate tracks for flights taken in the past or planned for the future. See attached screenshot of such tracks imported from MapSource.
