This is brilliant, I use shadertoy a bit to quickly test out where I've gone wrong in my fragment shaders (which is usually the whole thing).

This actually seems like it'll be much better for the job.

I'd love to see ISF export added too: https://www.interactiveshaderformat.com/spec

Holy crap how have I not heard of this? This already scratches an itch I have for no good vertex shader editors. I'm looking at the "composed" graph editor thing, a little confusing but it looks really powerful. Thanks for sharing.
