Feature Request: Hide Selected Playlist Option

Many of us have a lot of playlist listed below our Collection on the left side of screen which at times can be a bit of a pain to scroll through especially during live performances.  If all playlist had a checkbox near them which could be selected and unselected.  A "Hide Playlist" button or checkbox could be positioned preferably on main screen which would in-turn hide and un-hide selected playlist.  This would be an awesome feature.
