We're using a large tablet for our survey and we found very annoying that we couldn't get a bigger map on the survey screen. The map "box" cannot be modified though we have plenty of empty space to make it bigger. Zoom in and out in this small box is not very convenient. If we need to have a larger map view of the area we're working in, we have to tap on the map and jump to another screen, save, go back the the survey screen and save again.
It would be great to be able to adapt the map "box" on the survey screen or even better, the box adapts itself based on the room left on the screen :-)
