Great Add on - it removes all the annoying parts of Youtube and creates a distraction free clean look.
It is customiseable, you can select what you want removed. It even offers Darkmode for its menu - I love it! Some bad reviews are just because people are unable to click on the extension and select the option sliders they want - it is that easy.
By default the playlist sidebar is hidden, I recommend turning that of!
I think the extension is essentiel and happily donated a whole 4 $

Vastly improves the YouTube experience by allowing for extensive customization just for your needs. I really don't want to see any non-subscription recommendations, which this extension helped me accomplish.

Brilliant, instantly responsive, great adjustability

This is what i'm looking for. thank you!.

Einfach nur schön

I don't even remember how default youtube looks without this.

Excellent, helpful and works perfectly

Thank you!

Saving humanity one extension at a time

a little over the top by default with how much it takes out, but it's extremely easy to configure and takes a lot of the unwanted stuff out of youtube. config works with sync seamlessly on firefox. would recommend to get rid of stuff you don't wanna see. only complaint is redirecting home to subscription feed takes a couple seconds most of the time.
