When saving playlists there is no listing of existing playlists for the current preset, so I try to remember the proper spelling and capitalization of the playlist I want to update...but alas, I forget to add the hyphen or capital letter and bam! I have a duplicate playlist. Can't delete it. So the list of alternate entries expands and now I have 6 versions of my original playlist title. We need a way to delete playlists. Would also be nice to display the current playlists and select the one you want to update.
