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.

When I suddenly think there should be an add-on for batch selection playlist this add-on popped up from reddit. Thanks buddy. The feature of showing playlist name in the left navigation menu doesn't refresh or shows up. Temp fix is to disable and enable the option in the add-on. Please look into the issue. Also it will be good if there is a option for filtering unavailable videos in playlist.

An overall good workflow tool. But, it would be nice to have a "Hide" menu option for "Subscriptions", much like the "Remove from this list" for "Playlists".

Works extremely well ! I was able to migrate all my watchlist to a new playlist. Thanks a bunch
