Only needed briefly but was an incredibly helpful tool.

Absolutely brilliant. Only gripe I have is the pulsing donate heart, but if you have ublock origin installed you can hide it with a custom filter:
"www.youtube.com##[id^="msfy-donate-icon-"]"

Просто. Лучшее.

A must have add on
Thank you Pollux :)

This is in my top 3. WORKS! I assume creator in new version found ways to work around some YouTube limitations. "Select videos by title" filter is my way to create themed playlists from Watch Later. PLEASE, make SELECT BY AUTHOR too. And if possible - By Language.

I do not understand the bad reviews. The extension does not ask for important permissions and works perfectly fine for me editing my "watch later" youtube playlist. Very useful!

The new version took some getting used to, but now that I've familiarized myself with the new action bar, options and the keyboard shortcuts, I like it.

Edit to add: If you have any issues with the three-dot menu in the action bar not working, you might have to disable a conflicting extension. That happened to me – I'd apparently installed another extension for managing YouTube playlists at some point, and while it was enabled, clicking the three-dot menu didn't do anything for me, but disabling the other extension seemed to fix the issue. I didn't think to mention this until I saw a different review mentioning the three-dot menu not working.

About 3.0. Normally, I was able to confirm that it works on accounts that are not in use. The account has no playlists and no channels registered. However, it is not working on an account that I normally use. I can even select videos, but when I click on the three point reader in the menu at the bottom of the screen, the menu is not working. This is an extension that I have great expectations for improvement.

Really great! My only suggestion would be to bring back the option show the video index numbers in the subscription page. Great extension!

Great™ — Multiselect has become an essential YouTube feature for me. Google, if you’re reading this: buy Pollux’s code and integrate it.

Just perfect

Helped me get my watch later list managed until recently when the remove action stopped working

EDIT: Randomly started working again 5/5

ANOTHER EDIT: It recently got an Update and was working flawlessly, but YouTube made some changes that broke it.

You've got no idea how much I love you for making this extension, as someone who has playlists that are multiple hundreds of videos long (and prefers to have them organized,) I've been looking for an extension like this one for a little bit now. It works well, and the only issues it has are pretty much unavoidable as far as I can tell.

A life savor and Thank You for this awesome addon/extension ;)

This is a wonderful add-on to compensate for YouTube's inexplicable lack of playlist tools – which should be a core feature.
