Due to the limited memory on my phone (Orange SPV C600) only one or two maps can be displayed at the same time. Unfortunately I cannot manually enable or disable maps on the phone (if I don't want to start file manager and move them out of the directory) - or I don't know how ;-)
One very cool feature would be that only the map that is relevant to the current GPS position is displayed.
Anyway thanks for the great software, I like it very much!
