This is a minor niggle of mine.
I would like to be able to hide the "User" column on playlists which are not collaborative (or have never been collaborative) since the column will always say the same name the whole way down the playlist, and that users name will be at the top anyways!
This is not such a problem on a widescreen computer like my laptop above, but on my desktop with its extra little 15" screen the User column just takes up unneccessary space which introduces horizontal scrolling.
In my eyes the duplicated data is just not needed!
Update: This should now be implemented! 😉
