If you’ve ever opened several YouTube videos in a bunch of different windows, YouTube Doubler makes watching all those videos much easier.

YouTube Doubler lets you paste the URLs from these videos two at a time, then places the videos side by side. You’re able to have full control over each video’s volume and playback controls--a feature that enables you to instantly jazz up bland news pieces with fun music videos.

For those with especially short attention spans, the draw of YouTube Doubler is clear: You’ll have one fewer window open.
