I'm proposing two separate but related capabilities:
Export a text version of a course outline from 'Modules'
This would produce an editable file that could be used for course planning and revisions. The format could be txt or docx. It would allow an instructor or course designer to easily mark up the course outline to provide teaching tips, revision suggestions, etc.
Import a text version of a course outline to populate Modules.
This might need to be in a csv or specific markdown format, but essentially, a user could import a file to create a course shell. The file would need to be able to specify what type of module item to create, and it would create and title the modules and module items accordingly.
