YouTube PopOut is a free Chrome add-on developed by JIVE DESIGN. It allows users to pop out YouTube video pages into panel windows, making it easier to watch videos while multitasking. With this add-on, you no longer need to open a new window, resize it, and reposition your other windows just to watch a YouTube video.

Using Chrome's Panels feature, YouTube PopOut positions the popped-out YouTube video pages conveniently at the bottom of your screen, above all other windows. This allows you to keep an eye on the video while working on other tasks.

It is important to note that in order to use YouTube PopOut, you need to enable Chrome's Panels feature. To do this, simply visit "chrome://flags", enable panels, and restart Chrome. Once enabled, you can easily pop out YouTube videos into panel windows and enjoy a seamless multitasking experience.
