YouTube is testing floating picture-in-picture videos on the web

YouTube might bring one of its mobile apps’ most useful multitasking features to the desktop version. The platform has started testing picture-in-picture playback on desktop, a feature that continues playing your video inside a small floating panel when you navigate to other parts of the site. So long as what you’re watching is currently playing, YouTube will minimize and place it on the lower right-hand corner while you browse other videos. – Mariella Moon, Engadget
