Thank you for reading this. Like many of you, I put a great deal of time into my playlists, especially my smart playlists. Some of the smart playlists rely on other playlists which rely on others and so on. I worry because it is as simple as one keystroke to delete a playlist and, in turn, create large problems which aren't easy to fix. Is it possible to require double deletion on a playlist? Or, perhaps, is it possible to make a playlist "invisible" so that I isn't inadvertently deleted. Thank you.
