Control all youtube tabs from any tab any window.
This is a chrome extension which will allow you to play or pause youtube videos running across all tabs in all windows. Press the row containing title and it toggles the state of tab playing youtube video. You need to reload tabs once after installing the extension.
Now also supports jumping to particular tab and closing the tab.
The extension is open source so feel free to add any issues or pull requests on https://github.com/shahankit/youtube-playback-control.
