Allow playlist customization from any presorted order, not just oldest to newest.

[Btrain1]

I'm not sure what happened to the simple "edit" option in the right-click menu, but after spending almost an hour chatting with customer support to discover it was an "update" Spotify made. Up to this point, if you wanted to edit your playlist (whatever order it was in), simply clicking edit allowed you to do it.

But now, if you have an older playlist that was sorted "newest to oldest", but now you want to customize you have a problem. If you click sort/custom so you can move a song or two, it re-sorts the whole playlist into date added - oldest to newest, forcing you to start customizing from that order. I have some playlists that had already been sorted  newest to oldest and customized a bit. They are fine and I can customize. But any previous or new playlists I want to customize now will only allow that by beginning with the oldest to newest order to start with.
