It could be much more useful, if we can record a new waypoint on the air.
When we fly in manual mode, we could record a new waypoint, localization, altitude, and current camera angle, for example by a special icon available in main screen. Better: by right hardware button (it is not in use because such icon is always visible on the bottom-right corner of screen).
In this case we can collect all necessary waypoints while we fly.
Then we can edit such collection of icons in normal Flight Plan editing, fix some point, move some point or
delete, or just start to fly one more time with the same already recorded points.
This could add advantage: we plan points more securely, because we do not “ask” and determine altitudes from maps preview, but we fly and observe the drone on the air, and record where is safe altitude in every point of the plan.
One more: it could be additional feature: recording waypoints automatically, for example: every 15 seconds.
