Comment 1 for bug 887482

Thank you for taking time to report this.

It is more of a missing feature, than a software bug. We do, naturally, acknowledge it's a missing piece.

Currently to edit a playlist you can launch it (Play all), tweak the play queue, hit Menu > Save playlist and use the same playlist name as the one you have loaded. Not very user friendly or intuitive. However, we do have UI revamp on our roadmap, which should bring way better user experience.

Marking as wishlist for now.
