I create a lot of videos every day, and I like to stay organized by categorizing each video into the appropriate playlist.

However, sometimes I lose track of which videos haven't been added to a playlist yet.

It would be really helpful to have a feature that allows me to "sort by videos not in a playlist" so I can easily find and organize them.

View "uncategorized" videos (that are not in any playlist). This will help me tidy up a little bit...

Also, maybe next to each video put information about what playlist that video is in.
