Like most designs, we'll get used to it, but there are noticeable options missing. I agree with a lot of the feedback above.
I prefer the studio name/link being on the on the main page below the preview, the icons are so small as to be useless, so we have to wait/hover.
I used the main page "watch later" button next to "like video" a lot, and now it's below the 3-dot menu you have to hover to get to, then add to playlist, then select the playlist.
