Reordering Playlists!

After more than one year I came back to Watch2Gether today - but I can’t believe that there is still no chance to reorder a playlist. I already put the number of the year in front of the name of the video - but not even this simple order works! I think, that this is more than a bug - this missing function is a simple must have. And I am talking about the Pro-Version, which I bought today! Not possible!
