Lots of useful options for different kinds of workflows, in my scenario i have moved thousands of docs/pdfs from a legacy site and need the site admins to manage all of that content without ever touching media library (nightmare!).
This does the job, and lets me as a developer ensure that it's secure and easy to use.
I think if the author could improve the default design and clean it up, even more people would use it.
One small problem I ran into is that all of my files/categories are showing up in my sidebar, even though i have never enabled the widget for it. Is this a bug or just me?
