I came to an idea...
Add ons are mostly scripts, meshes and textures.
I may suggest to make an automation app.
Right now I am working on a scenario creator for Orbiter.
I got to understand how to build scenarios and I am making an app.
I figure myself that something similar could be done for Celestia.
I'd do it, but right now I am trapped with such an app project for Orbiter.
However, that's the idea. Any dev here could take the idea and develop it.
