YouTube has introduced some new changes to the homepage feed, including bigger video thumbnails, more information about uploader activity, more user control over what appears in the feed, and labels for videos you've already watched.
"We restructured the design to show bigger, higher-quality thumbnails," says product manager Kurt Wilms. "We’ve also included more information related to the video. If an uploader has commented, posted, or added a video to a playlist, we surface this information so you can get a better picture of all the activity related to the video."
"We’ve introduced a menu that lets you quickly control what content appears in your feed," adds Wilms. "To bring up this menu, simply hover over an item in the feed and click the arrow that appears in the upper right of the item. You can then choose to hide the item you have selected, opt to only show uploads from that user, or unsubscribe from that user, all directly in your feed."
Here, you can see these features in action:
And here's what it looks like if you've watched a video:
YouTube also reminds users that they can always click "view" at the top of the feed to either see only highlights or everything from the accounts you follow. It shows highlights by default, so you may be missing some things.
