Very, very useful. One aspect I would like though is being able to use the modifications to videos and that they would be applied when downloading the video.

ここまで素晴らしい機能補完は見たことがない

Edit: I am now having the exact opposite problem I had in the past. The extension only seems to work in private windows now.

Amazing extension however recently I’ve noticed that it no longer works when using in a private window. The … doesn’t appear anywhere, keyboard shortcuts don’t work and it doesn’t even automatically disable autoplay anymore (the extension still does shows up in the overflow menu though). Works fine in normal windows and has many useful features so I still highly recommend.

Fantastic add-on that works, has useful features and simple to use.

Muda totalmente a forma de assistir vídeos. Facilita a vida, mesmo para assinantes do serviço premium do youtube.
Só uma coisa que eu sinto falta: logo no começo, nos controles do player, para cada ícone aparece um "i', que mostra uma pequena explicação do comando. Esse recurso é bem útil e não aparece nos controles de volume.

The only things missing from this extension are :
- an option to stop the really bad and forced youtube function that translates the videos titles into our youtube langage setting. Its cheat us into thinking that's a [isert your language here] video while it's in another language, and more over with a really bad translation...
- more flexibility with the overlay vide : when we scroll down, be able to move the mini video playing where we want on the screen on the fly (the current solution forces to hide a specific part of the information, either part of the comment section or the suggested videos, and you are force to find the "X" to close it or move the page at a specific height to see what you want). With such feature, we'd just have to grab and move the video , quick and clean.
