This add-on is really helpful with YouTube's absolutely awful playlist management. I do wish the multi-select "Save to playlist" option actually worked, rather than needing the "Add to queue" workaround detailed in the "About this extension" section -- but even with the workaround, it's a big time-saver.

The best extension ever made for YouTube. It's a shame that YouTube itself doesn't have this ability or anything like it at all.

Cette extension rajoute des fonctions supplémentaires sur YouTube:
● Sélectionnez la vidéo {0} à {1}
● Déplacez après ici (un ensemble de vidéo)

Please add an option to add things to a playlist (if you are in a playlist marking things)

Edit: I mean it would be great to select videos in one playlist and then be able to add them to a different one
