Mkramer1974 In app- if you expand the Playlist menu on the right hand side, you can move the cursor over any of the videos in your playlist, click on the 3 dots that appear, and it will give you the option to delete that specific scene from the playlist.
Likewise, if you move the cursor over the playlist name itself towards the top of that right-side menu, you can click on the 3 dots and the pen icon to rename that specific playlist.
Not sure if these were specifically what you were looking for?
