Some filters for ublock origin to make the youtube ui more minimal and less distracting. I found most of these on r/ublockorigin, and by using the point-and-click feature.

Removes shorts, feeds/recommendations, homepage, and the weird trending searches.

I use youtube signed out in a private window so this is some other stuff I remove. I find comments distracting and not useful so I removed that as well.

! extra stuff I deleted like side menu, guide, and icons on top
