Playlist Folder Behavior

First off, I am LOVING Rekordbox DJ. As a working DJ and a longtime owner of Pioneer DJ hardware, I can see myself migrating to this app as my primary DVS software. I don't have many deal breakers but this is one..

Playlist folder behavior: Collapsing a playlist folder shows the playlists within the playlist folder and selecting the playlist shows it's songs as expected. What's odd to me is when selecting (highlighting) a playlist folder, I would expect that all of the songs contained within the playlists of said playlist folder to be displayed. Instead the songs section stays blank until selecting one of the playlists. Having a hierarchy of playlists is useful with my workflow. I hope this is something that can be added. 

Look forward to hearing back. Thank you for developing amazing DJ software!
