Youtube completely turned black after installation. Maybe it was interfering with another extension, idk. Once I uninstalled things went back to normal.

- For the record uBlock Origin was installed prior to this. Again, I'm not sure if it somehow conflicted with this extension or not. I might consider a resinstall in the future should anything go wrong with the current setup. For now, things are fine.

Thank you for responding. Although I have no desire to reinstall the extension, it makes a world of difference when attention to a particular issue is given. Thanks again and take care.

Can hide the right-sidebar, but cannot center the video like in the screenshots on the main page.

I like how it removes all the video suggestions below any videos I just watched, so I don't have to scroll down ten meters to get to the comment section, which is the interesting bit. That is the reason I installed this extension. It is completely beyond me why youtube changed its layout in this user-unfriendly way and I hate them for it.
However, this add-on also removes all the video suggestions from the youtube starting page. But when I call up that page, the suggestions are actually what I want to see. I do that from time to time. There is a time and place for everything. This should be configurable.
