i think it would be nice to have a separate floating configurable panel with buttons, sliders, xy joystics etc. User could create their own presetsand name the outputs. Then user could use panel node outputs to controls morps, displacements, etc. I think this would be very powerfull feature! I could do mocup of this but now im on phone only.
Also user could do multiple panels and select which panel user want to use on panelnode output. Maybe also opengl version too
