I would also very much like to see this feature. I accidentally rotate the map probably half the time when trying to zoom. Either that or make rotating it much less sensitive on touchscreen devices. I currently use a relatively slow Android tablet as my EFB so it’s extra annoying as it takes a couple seconds to reset the orientation. I also don’t think I’ve ever had the need for my map to be anything other than north up, so personally I have no need for rotating it in the first place.
