Better than the twitch player. Twitch standard player, if hiding both side panels, always shows channel info below the video, leaving black bars on either side of the video because the website doesn't expand the video height to take advantage of all of the space.

This extension allows the player to be bigger, but it's still a pain not having a popout menu that shows my followed streamers. I have to exit the page and return to twitch to view other streamers and people I follow. A simple toggle similar to the chat would be great.
