Correct, DD only accepts polygons at this point. Litchi does as well as paths and points, but it turns them all into a traditional point-to-point flight. It is $24-25 and worth it’s weight in gold for its versatility.
In Litchi you can be flying and planning a mission at the same time. So I manually fly what I want and set the waypoints at my positions. Then if desired I can set the POI’s and dry-run to get them right or just manually control the yaw and pitch of the camera. The granular control of the points allows you to control horizontal, vertical and heading of each waypoint independently as well and the position and vertical of each POI.
