Don and all,
We are currently working on taking our Hi-Def Charts to a "Seamless" approach. The iFly GPS software does automatically switch charts at this time, however you do see the borders. With the new approach, you would not see the borders, however they would still be accessible. Stay tuned on this upcoming feature.
FYI, we are also adding in Fuel Prices, FBO services, etc in the very near future as well. We have an understanding the many pilots like FF for their planning, and then iFly GPS for actual flight. We are highly committed to improving our planning feature set to make iFly GPS the best Planning and Enroute App.
Thanks for the great feedback.
