I’ve absolutely loved being able to manually map missions using Litchi. It’s super awesome. I’ve actually been able to manually map missions for 2D and 3D mapping with a bit of work, but it takes a long time to map it out with the current layout.
If we were to be able to use the Draw feature on iOS/Android to draw a square, and have it automatically space out a grid based on parameters (spacing between passes, change orientation) that would be a huge upgrade.
In the same vain, you could provide circles to be drawn for orbits instead of manual waypoints. This could be used to plan a mission in the hub with a quick spherical orbit with a focus on a POI.
