Based on Don Hinkelman's project course format, and Martin's comments here

http://docs.moodle.org/en/Development_talk:Repository_API#Bulk_operations

there is a need for some new options(s) on the resource drop-down so that:

• multiple files, or a folder to be uploaded to the repository at once
• multiple files can be uploaded at once and be automatically added to the course as resources with their names automatically generated from file names
• Find a group of files that are already in the repository and add them all at once with names generated automatically as above.

Or some variations thereof.

Don's course format does this using drag and drop so that files can be added to the course super-easily. Could this be an optional feature for all courses?
