I would love to have the ability to combine multiple flights into a single flight. I find that I might fly multiple flights in a single day, or make landings in a single flight, and the app registers as a new flight each time. I tend to export directly from iFlyGPS to MyFlightBook.com, and having this feature would make it easy to enter the flights into the logbook. In the past, for huge cross-country flights, I have downloaded the data, and concatenated the GPS data files into as single file, which works great, just is just kind of a pain to do.
