Agreed, I always need to scroll to see video description content and comments which I would rather be able to see while still watching the video.

While, instinctively, the previews below the video feel odd because they've been to the right for so long. Logically, I can see the improvement they are going for here and would welcome it.

I have the Enhancer for Youtube extension which solves this problem.

And maybe I'm being an anti-change curmudgeon but the previews below seem to be putting more emphasis into engagement chasing social media by having Google try to convince users to click one more video. It's more distracting from the video you're watching than having it to the side in a widescreen monitor.
