Allow Downloading of offline Aerial/Satellite maps in the Maps app. currently maps app won't work on Aerial when offline. we're using computers/laptops/tablets and other portable devices with massive amount of storage available, there is Already an option to choose another drive or partition for offline maps storage, plus for a single state or country it shouldn't be so big. it'd be a great addition to the app if you add this option.
you could also add some miscellaneous settings to it, for example specifying the zoom level which can have a big effect on the size of the maps, the expiration date for the map files and how often they should be updated.
