Shader parameters

Is there any way to add parameters as input ports to the shader node?
Having fun writing shaders for realtime image mappings but having to hardwire constant parameters is “messy”.
Yes I know about the method concatenating shader code and external text together outside the shader node, not so elegant either. :-)

Feature request being implemented — Ability to edit GLSL shader code in Vuo Editor.

Currently, you can use the Parabox GLSL nodes or write a custom node class containing the shader.
