Features: view media not in categories

First off thanks for this plugin. I created my own but it was not as advanced as yours, mines was missing the dropdown features.

Is it possible to view media that are not in a category?

On the details tab in the screenshots there’s an image that shows the option to view all categories when inserting media, but I don’t see that as an option. Is that an option in the latest version? If so how do I activate or access that feature?

Thanks.
