Why no 'Edit Playlist' in iTunes 12.7
"Edit Playlist" used to be so simple. Easy to do and easy to see and easy to adjust. Since upgrading to 12.7 it is no longer so easy (or even possible). I spent more than two hours with Apple 'Support' and after trying everything known to them, they eventually phoned Cuppertino and found that the 'Edit' facility has been changed to something else so user-unfriendly that I was unable to understand it. This also affects the ability to create a Playlist. If you value the original means of creating Playlists, I urge you to contact www.apple.com/contact/feedback.html and ask them to re-instate the previous 'Edit Playlist'.
