Having seamless maps is nice but keeping the option to use the full sectional/IFR etc is a great feature. I still like to have the legend and other information available on that sectional. I find this a good feature of Ifly. I'm currengly using (andriod) Ifly beta, naviator, Garmin Pilot, Avare, and Avilution. Ifly has the best features of them all but is still buggy (beta) at this point. None of the other programs show the legend/sua that is around the chart.
