After downloading a few topo maps, I found two good ways to improve their use.
First, those green boxes that show downloaded regions are really only useful when you’re managing your downloaded maps. Once you’re trying to use the maps, they actually hinder the view. These screenshots show two overlapping, downloaded regions. The green boxes eventually go away if you zoom in close enough, but you have to zoom in so far the map is nearly useless. The image on the right, is zoomed in at the intersection of the two areas at a zoom level that makes the green boxes disappear.
Second, I don’t remember the order that I downloaded regions, so my current options are either delete one and switch to the map to see what disappeared or delete all of them and redownload new maps. What I wish I could do was tap a slot to see it’s downloaded area. Bonus points if I can toggle downloaded map indicators to see those green boxes labeled with the slot number each one occupies.
