This looks really great!
To be honest I tend to tinker a bit in the simulation space so this all is really interesting. It seems like a github pledge is better for you than patron at the moment, as you keep all the money, would you prefer that?
I'm glad you like it! I'm trying out both GitHub sponsors and Patreon at the moment to fund more projects, I'm not sure which will stick! So far it looks like Patreon has better support for giving back to your backers, but GitHub also doesn't take a cut. I am of course very grateful and flattered - please choose whichever you prefer!
If you are thinking of making patron only content then that's better.
Hence why I was asking ;)...
