offline maps: 3 improvement

HI, It would useful:
1) to see in the main screen the border of all the maps present in the map folder. I need this in order to check if an area where I have a track is all covered by my maps.
2) to mantain the map zoom: when I pass from a map to another map the program automatically zoom to 100 (by default). I've seen there is the possibility to variate the zoom level but it would very useful that the program mantain the same zoom level of the previous map. In fact I divide the big maps in a lot of sub maps and if I zoom I have a different view when I pass to the next map
3) to open at the same time 2 or more maps: this is useful to study the track before ridinig

Thank you very much for your great work

This would probably bee too much for reduced resources on the phone but option to have two maps preselected and being able to quickly switch among them would be really helpful.
