This addon has made YouTube a much easier place for me to learn from. I mainly use the site for education purposes, so having stuff like sidebar recommendations, comments, and a bunch of other nonsense alongside it makes it difficult for me to focus on what I need to do.

Sometimes I'll get sucked into recommendations hell where I'm staying up until five in the morning watching all the videos I have queued in separate tabs (knowing how to middle click links is both a blessing and a curse). There are times where I'll even get sucked into debates in the comments section where the only thing I get out of it is brain cell depletion.

So yeah, I'm really stoked to have this installed now. Just having that one single video on the screen and nothing else feels soooooo liberating. It's a million times more comfortable than what it was before, and I think I can study a lot more efficiently now. Blocking out recommendations and comments will probably help to preserve my sanity in the long term as well.
