Doesn't 'Direct to' show most of that (without factoring in wind etc.)

Another "nice to have" would be an Emergency Button or Tab which when activiated would show all (or any) airfields that are in gliding distance of your current position/height, taking into account winds etc. If a Tab it would show all required relevant airfield info, runways available, surface, lengths, airfield frequencies, blah blah, nothing like being armed with information to make the best possible decision in a high stress situation. As I say a nice to have
