Amazing thank you. Still works despite not being updated in over a year. Just grabbed over 200 videos from my watch later list and added them to a new playlist in one go.

Amazing add-on, automatically detects how many videos are in your playlist, can copy the entire playlist or save as a file locally, and import it onto another account instantly. Thanks so much saved me tons of time.

Works flawlessly

Unfortunately, dont' work on yotube history menu. Is there a way I can return back to the previous version. if Maybe it would work again.
And it is no longer possible to cut away from a playlist; I can only copy

Doesn't work for some reason

It's really nice but lags your browser like crazy when viewing a large playlist, even when it isn't being used

Works mostly, but lately, attempting to delete videos from playlists results in a "Precondition check failed" error, and the videos do not actually get deleted. Adding to other playlists, multiselecting, etc all work fine, but deleting kicks back an error. Still worth it though!

Used to work perfectly, but now it doesn't actually delete vids when it says it does. Still saves a ton of time transferring vids between lists and definitely worth the download.

Deleted it briefly because I thought I found an alternative that did this and a few other things, but it sucked. Great job on this! Developers like you are always appreciated.
