A way to make custom GUI's for nodes. These node UI views could simply be Vuo compositions which are triggered to run when either a button or in node event is triggered.
So for example if someone designed a synth node with a GUI then we could use that GUI to change sounds - and also allow end users to activate that GUI view in app or in composition.
Whatever values were changed would be sent to the node, and closing the window would end the compositions view.
It would also allow node developers cool ways to allow interaction to nodes. Such as audio editing tools, which are hard to do 100% in node data ports.
I think it would be a shame not to use Vuo compositions for this UI view - as it would allow developers to use their understanding of Vuo to generate the nodes UI itself.
Not every node need have a UI - specifically for nodes that need them. (Data editing tools- text tools- audio tools - timeline tools.
