I nice feature would be the ability, while on the waypoint editor screen, to switch to "Altitude mode" and see the right side of this image, instead of the map. Then be able to touch and drag waypoints to the desired height.

Currently, you have to click each individual waypoint and set the height. This change would make altitude setting for each waypoint MUCH faster.

Additionally, another update could add SRTM data to this profile screen so you could see the "estimated" terrain height that your waypoints will be flying over, which makes your altitude settings more "educated"
