This handy program allows you to open any of your favorite YouTube videos in picture-in-picture mode, which lets you continue browsing the web while the video plays in the foreground. It also includes a number of features like skip and next buttons, and you can even search for related content. This is a very useful feature especially if you have a limited amount of time and don't want to miss out on anything.

It works with most recent versions of Chrome and Safari on macOS.
