Oh - whilst I’m doing explanatory diagrams for Litchi - and in case anyone doesn’t see the potential danger of “inserting waypoints when using height above ground mode” …

Assume the 4 black waypoints exist and are set to x feet above the ground … and you realise you need to get over that hill and need a waypoint (green).  
If you select the waypoint before the hill and click insert, you’ll get the real mid-point (red), and it won’t clear the hill.
