As someone who is learning Grasshopper, I wish there was a reference for Grasshopper as good and similar to the Rhino help/reference.
As a new user I want to know what each component does, and have an example of how to use them–in the help/reference.
Currently, there are many tutorials which tell us what to do, but I find it difficult to know what I am doing, without knowing exactly what the components I meet–does.
As a learn, I am forming a list what I don’t already know, I realize that it would help me if there were more information about lists and the data tree, which seems vitally important to be competent with Grasshopper.
UI-Wise, Grasshopper is neat, though I wish I could dock it to Rhino with more integration, and perhaps similar icons.
I also wish that the icons were also visible for the components after you lay them down, at some zoom level. Still, I am amazed at the coding for the wires, and that it all works as well as it does.
It would be handy if as you created, say a integer number input, if the value were automatically placed as the legend, such as int = 5, otherwise panels will continue to be attractive numerical input components, which will circumvent type checking and slow grasshopper.
