I you liked where Autopilot left off you might want to check out Dronelink. The same creator is getting a new mission planner off the ground.
It is out in Beta.
I have only been working with it for a couple of days but so far I am impressed with the start they have made.
I have flown several missions that did exactly what the built in Preview indicated. The framing seem tighter than what I typically get with Litchi. And so far no unexpected behavior that wasn't caused by me.
Fun, powerful and flexible. As it matures and I get better with it I can see it becoming my go to Mission planner.
