Many users when they open a YouTube video, they stop it, scroll to read the top comments and then go back again to watch it. It would be better if during the scrolling, the video was staying at the top of the screen so that it wouldn’t be lost, allowing the user to watch the video and read the comments at the same time.
The Video Pinner extension for Google Chrome does this, which after its installation is displayed on the upper right part of the browser and pressing the icon at a time when the user is on a YouTube video page, the video gets pinned on the top of the screen. We hope in the future, this extend will have the ability for automatically pin each page of YouTube, since manually doing so is a bit boring to do every time.
