Enhancer for YouTubeの代替でこのアドオンにたどり着きました。似たようなアドオンはいくつもありますが、どれも英語で項目も多くすごくわかりづらい。ここのアドオンも項目は多いですが、やはり日本語だとだいぶ理解しやすいので有り難いです。

Best extension for YT! Please add function disable thumbnails and title in capital letters

works well, with a LOT of options

Extremely useful addon.
Lots of features, makes the experience of using Youtube way better, to counter the fact that Google tries to make it worse and worse each year.

I'm not one to write reviews often but I feel the need to for this add-on. Firstly, my biggest gripe recently is YouTube's UI "improvements".
This add-on lets me clean up the home page's sidebar to get You(history, playlists, etc) back where it used to be. I then switched Subscriptions to be on a link below the Home link, easing that burden so I'm not hitting a subscription instead of history like I have been lately. Also was able to make the videos and thumbnails squares again, which I love.
I just started playing with the add-on, so I might not have seen it or it might not be possible to do, but the only thing I wish this included so far is to remove the drop-down menu next to watched videos in History and bring back the X that was next to them for the longest time.
Aside from that little thing, I absolutely love this add-on, and the developer genuinely has my highest respect for this. So thank you!

没有UnTrap好用，太简单了

making the site usable again

I only got it for the 'Hide watched videos' feature, and it doesn't work.

Much neeeded addon, lets me continue to use the scroll wheel for volume controls provided by Enhancer for YT. Why does Google always have to change the YT UI?

Thanks finally i can turn off this AI retard voice

It doesn't work to hide those dogshit members only videos. Which I'd give anything to make those MFer's gone forever.

It's a cool extension, essentioal with that new shitty UI. But can I ask for you to do something with "add to playlist" option, so you can, as before this new shitty UI, add one song to multiple playlists without the window being closed after each.

Thanks you so muc, hope you will read this.
