With all the new plugins people are making that use reference files as an input, would it be hard to make a component that when double clicked we could browse to a file to use instead of using notes and typing in the full document path?
Ideally, I think a 'file path' parameter component that would allow you to browse for files, or drag and drop to make a list would work best. For many of the Local Code plugins, we use filepaths as inputs, and I was just trying to figure out how to make such an interface for a gis import component.
As people develop more interoperability plugins, I think we will see a greater usefulness for filepath inputs.
Or if the Panel component had a drag and drop capacity to convert dropped files to file paths.
Added a very generic File Path parameter (in the Params->Primitives dropdown). It allows you to select one or more files off the harddisk and it provides the full file paths as String output.
