Hunting for YouTube tabs is a giant pain. I created a Media Manager for Chrome

Most of my days I have lots of YouTube tabs open. Some of them are for podcasts, one for background track or others maybe some interesting video. And I have always been frustrated by this problem of hunting for the Youtube tab to pause the video or reduce its volume. So, I created this chrome extension to help me with it. It's a tiny thing but it does solve my problem elegantly, so I wanted to share it with the community. Looking forward for some feedback.
