My main one is that it seems like when in fullscreen map mode (or even when it's just in the top half of the screen), there's no way to get to the other functions on the top of the screen, without collapsing the map to the bottom half of the screen. That's awful UX...why can't I tap on the top part of the screen and have the icons slide back into view? Am I doing something wrong or are you really that trapped when you have the map up top?
If I tap anywhere on the map the buttons (top icons and map icons pop in) slide down.
