I think/hope current nodes a described in the software as a script language like XML or SVG. If not this is definitely a request for the 4.0 version.
I mean current node design and propertys are manly defined by a programming language.
So it would be good to have a tutorial, how to create new node designs. So I think it is OK when some programming skills are needed to create new designs but this should be an open API (for the future)!?
Thanks, Tuoyal
