I don't know if you've discussed this or not prior, but I think I'd be very useful to have the ability to download an app for this and save the cities to your device, being able to access them all in one app and editing them from there. Personally I'm using these maps for my  D&D game, (giving credit of course) as a temporary solution until I can find someone to make full maps. 

It'd be very useful to have it downloadable (and hopefully for Android)
