QT4: Add move up and down buttons to playlist window
As requested in: http://forum.videolan.org/viewtopic.php?f=14&t=66048#p220092
Some people would want up and down buttons to playlist window which could be used to move playlist items up or down (so instead of dragging the items around, you can move them with click of a button).
