Hello, new user here.

How can can I drive an exposed input, for example Hue in the hsl node with the result of another node - such as the luminance of a noise?

I suspect if its possible, I need to use functions with samplers, but I'm not finding the documentation for this area of the program very helpful.

Also, is there a reference for function elements and library functions? Some are obvious, others less so. There are lots of useful looking pre-made functions in the library, but I can't seem to figure out how to use them.
