I'd love to be able to click on the progress bar to jump ahead or back in the flight path. Perhaps the display on the back of the seats could show the actual flight path imposed on a map, and we could click anywhere on that flight path to move the plane there.

When selecting departing and arrival airports at the beginning, it would be nice to be able to click on the map to select the airport, useful if you don't know the airport code or the name.
