Feature Idea: All the dimensions!

[bid]

Feature request:

Why stop at three dimensions, when adding red and green to the 2d-pane could give us five?

Background: I am planning a game engine, that should use procedural textures.
While fiddling around with how to have a nice editor, I realized, that Shadershop has everything I need. If there were red and green channels, Shadershop itself would be a complete editor for procedural textures. All I'd absically have to do is plug the resulting formula into my engine.

It would feel weird to reinvent an editor, when one exists, that does 99% of what I need.

And then we use change-over-time for the next dimension and then a 3d shape for the ones after that, but I may somewhat get ahead of myself... ;)
