Currently, we have file_select(), which allows the user to select a single file in a dialog, and file_next(), which allows the programmer to iterate through all files in a given path.

I'd like to request two features:
1) Ability to select a folder with a dialog box.
2) Ability to select multiple files in the same dialog box. Maybe output the list of files to file_next().

Put on the to do list. The new evaluation shell can select folders, but that happens currently by selecting a file inside that folder.
