@alexmitchellmus asked on https://community.vuo.org/t/-/5239:
how do we make it so drag&dropping works with files? So that when I drop a .scl [file] onto the canvas the correct node is initiated.
Currently there’s no public API for that. For this feature request, a node class would be able to specify the file extensions for which dragging-and-dropping a file onto the canvas should create an instance of the node class.
