Can you add an export to txt and png button?
This generator is so good its planets could be usable directly. If I had a rectangular png map of the surface, I could show planetary locations clearly.
Thank you for considering at least. I've spent the last two weeks finding and testing different various planet / terrain generators and so far your one has been the best. If it helps, try this resource: https://eligrey.com/demos/FileSaver.js/ (right-click view source)

It's the same thing but with the ability to download the Planet as PNG (but not the Rectangular surface of the map)
