SDK for Shader Forge

Hi! First of all, let me congratulate you and say that Shader Forge is fantastic, an opportunity to discover (and learn how to code) shaders.
My question is: would it be possible to develop "black boxes" for Shader Forge? (in the sense of, for example, "add" box, which 'simply' add two objects) Have you thought about release some kind of SDK? 

(Specifically I'm working on enconding floats in RGBA textures, in a rough way, to use these floats on the shader)

Thanks for your attention
