Hi @Francis-6 I agree it would be alot easier to pick the regions if they were displayed as a map card rather than a list.
MRA is not the only one to present a list for the options of the maps, it is quite a common format even if it is not the best.
Osmand has a nice featue where it displays a basic map with very limited detail for regions where the offline map has not been downloaded. When you zoom in on a region it pops up the option to ask if you wish to download so you can see more detail.
Unfortuantley if french regional geography is not your strogest point then the only option with MRA at the moment is to google "france region maps" & work out which maps will fit the areas you want, maybe like this one:- https://ontheworldmap.com/france/france-regions-map.html
