Select Map download by coordinates.

This is a suggestion, not reporting a problem.
It would be a great help if there were a better way of selecting maps for
down land than drawing on the map. This is tough when you need more than just
a small area. Maybe be able to enter the corner coords of the area to
download. Also a way to verify that all of the maps have downloaded. I have
found it necessary to pan across the area that I downloaded to verify that
all the maps loaded. This is very important before heading off on a hike in
backcountry. Again I'm loving the app and not reporting a problem just a
suggestion for improvement.
