Feature request: add the ability to save/open the offline maps of a certain country or square area
I.e. "maps.me" Android app offers to download the whole countries, and some other apps give you the ability to save the large land areas, to open and view/zoom them later when you don't have the Internet. However, the only feature google-maps has - is to "Export as image" (like a screenshot), which obviously can't be zoomed to see more details and therefore is clearly insufficient for the professional travelers.
