I would like to be able to rename a playlist after I create it. I use rather descriptive names, and after using the playlist for a while, I might think of a different name. The only way I see to do that (now) is to delete and then re-create the playlist under the new name.

I’ve searched the forums and see that this point has arisen before, but those threads appear to be closed.
icon on the playlist to edit it. There you can change the playlist’s name or add a poster/description.
