Every new layout they try always gets rid of the drop down that lets you separate uploads from likes/comments. I don't care about the likes/comments of my subscriptions. Quite annoying having to go through all of them just to find whats been uploaded.
Edit: I see the screenshots from the Google System blog has the "uploads only" option. So maybe not all the new layouts.. Just the layouts I have had access to.
Edit2: Found another post about new Youtube layouts: http://googlesystem....experiment.html
