An extension that adds a menu item that shows an alphabetical list of your playlists to the left side menu.
As YouTube does not have an option to show playlists in the leftside menu in alphabetical order, I created this extension to add an item "Playlists A-Z" before the regular "Playlists" menu. Click on this new menu item to toggle the alphabetical list of your playlists.
This is a personal pet-peeve-project, so it works on my computer, your mileage may vary! If there is enough interest, or suggestions, I might update it.
2015-10-30 Updated broken code caused by changes in YouTube's HTML code. This also means that the alphabetical list isn't shown as a popup/hover menu anymore, but integrated in the leftside menu.
