In the latest Spotify library redesign, when I try to add a song to a playlist, the modal that opens sorts my playlists in a seemingly random order. This is very annoying since I have a mix of many playlists/folders in a specific custom order, and now finding the correct playlist to add a song has become a pain. This has only become a problem in the latest update, and worked perfectly in previous Spotify versions. I think that the order of the playlists in the "Add to playlist" dialog should follow the same order as the main Playlists tab - that is, if I have my playlists sorted by custom, the dialog should be sorted the same way.
