Thanks for updating this plugin! It's very valuable.
This is a feature request: The ability to add URL links as documents. The way the plugin is configure now you can not.
Why? Users simply want to share a Google doc or other online document with the group. This would be a nice way to categorize and keep them up to date.
So in this scenario maybe there would be an 'Add a Link' button in addition to the 'Upload a New Document' button.
Let me know your thoughts.
