Sounds like you're using an old version of Unity. Which are you running?

Thanks for posting :)
Will look into this later

Sure!

I think it works, but it's positioned incorrectly/on the other screen, right?

The goal is to make SF able to generate the entire shader from only its metadata, at some point, so I don't want it to read from the code itself.

It's not 100% independent, it reads the shader name from the code, but the rest should be indie, I believe :)

I still want to do this, it's, like you said, just a bit of a messy thing to solve, interface wise!
(I'm quite picky when it comes to interface design)
