I keep opening videos on another tabs unrelated to what I'm currently seeing, this doesn't allow me to focus even when I need to study a certain subject (yes, sometimes I use youtube for studying).

So I just created some CSS and JS, to hide elements, that's it, simple solution.

If you want to install the extension you can do it in this url: https://chromewebstore.google.com/detail/minimal-youtube/emc...
