The playlists may be easy to create, but not to edit. It is just a big list of playlists, which is fine for 10 playlists, but with many playlists, the scroller is a killer…
I imagine it is possible to have a dedicated screen to all playlists, better to view them and edit them, I don't know exactly, maybe also something where I can find a selector of playlist I wish to view and/or edit, they appear on the screen, plain, I can compare, drop, drag, delete, a search field to add (with a search result that doesn't cover my playlist but let me drag in the playlist I want)
something Minority Report, say. But with a mouse, or trackpad, would be enough 😉
