@W0LFB3AT5: At least for me, Maps automatically asked if I would like to download area I'm mostly visiting to offline - also to rate/answer stuff of places I'm usually visiting. But my operator only offers unlimited data plans, so there's not much point.

@Mario69: usually by now with the location you constantly go to repeatedly, that it wouldn't even bother adding extra data to it, you know? Like it should be saved into your inventory automatically or something like that...
