Combined list - Merges your subscriptions, friend activity, and recommendations into one easier-to-scan list
Don't miss a video - If a channel uploads 4 videos in a day, you'll see all 4 - instead of just the latest video
Delete anything - Hover over any video you don't want to watch and click 'x'
Or just grey it out - Videos you've already watched will be greyed out - so even without deleting, you'll know where you left off
Help me re-find stuff I just watched - Your homepage will include your recent likes and favorites so you can easily get back to them
Easy inbox - Links to your inbox (personal messages & comments) are front and center
Load much more - Watch older videos - all without leaving the homepage
YouTube wants to create a more comprehensive newsfeed that includes your actions and all the actions shared by your subscriptions and friends. Unfortunately, the homepage is no longer customizable.
