Fantastic. A bit confusing to learn how to use (mainly around the Playlist Builder; what is it, why is it not in the sidebar), but can now completely ignore Youtube's deliberate and growing amount of annoying design choices. Faster, easier and more convenient to add/remove videos once setup. Future-proof against YT shenanigans.

Would love to see the following additions to make it perfect:
- A "move to top/bottom" function to help w/ playlist editing
- Auto-save playlist upon moving an entry
- Something to help w/ playlist page management, either by increasing the entry limit or making moving entries between pages easier

no way to edit existing playlists

Seems to work well but is there a limit of 50 videos?

Can't correctly save playlists of over 400 videos. Sometimes number of videos in a playlist is wrong.

doesn't load your youtube playlists

The update adding pages to playlists is good as it lessens loading times, but I would like the option to choose how many videos appear in a page. As low as 5 or as high as 20, for example.

A search function to find the videos you're looking for would be great too. In addition, I can no longer manually organize the videos in a playlist, please fix this.

Finally! After all this time that I've been looking for an extension that creates a playlist from multiple opened youtube tabs, the queue feature is great but it only lets you create a playlist on the tab that you are currently viewing but if you've opened another tab, you cannot add the video to the same queue, which makes this extension come in handy because you can now combine all of them into just one playlist in one tab!

MEU DEUS QUE COISA ÚTIL. TÔ PASMO. OBRIGADO. :D

Great Extension. Difficult to understand why this functionality has not been provided by YouTube. I created only from links (limitation is 50 links). I would advise to use Firefox Add-ons Manager to change the options first. Also create an empty playlist in your YouTube account. Then use the « YouTube Playlist Helper » and finally add the temporary list to your own.
