In Litchi, a mission needs a minimum of 2 waypoints.
But, this is no bad thing since a first one above take-off to clear trees/buildings prevents the risk of it straight-lining from take-off to the desired waypoint.
You can pre-set camera heading and pitch at the waypoint, too.
AND … you can plan it, in advance, from your computer on a large screen rather than a small phone/tablet … and then fly the same one as may times as you want.
Actually - I have something in mind where I’ll be doing just that - a very tricky bit of flying between “things” … which I will fly slowly, record WPs as I go - and save the mission.
Then I’ll open the mission on the laptop, to make some smoothing tweaks to it, before saving (it syncs automatically to your device) and then fly it … slowly at first, then faster.
With Litchi - if you save a waypoint at that point - it does save all that info.
You have to be in WP mode, without running a mission, and just fly manually to the location and add a WP - then save the WPs you’ve created as a mission.
