'Smart Youtuber' is a simple application which is focused on making your YouTube-ing session more convenient. It does so by automatically pausing/playing videos in other tabs based on your current tab activity. The following two-step scenario sums up the application behavior -- Step-1: You are playing some video in tab-1. You now open a new tab-2 and play another video. The application will automatically pause the video in tab-1. Step-2: Next, if you pause the tab-2 video, the application will automatically resume the tab-1 video. This can extend to any number of tabs or windows. NOTE: This works only on www.YouTube.com at present. Videos in embedded mode are not supported.
