Hi,

After some experiments, i really found the Nodeditor is nice.

But it could be improved a lot. Imagine that you want to collapse all the nodes into one assembly. And maybe load it from a Node library. It could be awesome.

we could immagine that some Input Values get exposed, and then the Output get exposed too as a result.
