Best for Dota 2, LoL, Hearthstone, CS:GO, etc. Overcharge combines Twitch, Reddit, YouTube, and Twitter into one polished interface.
A stable work-in-progress that allows you to move quickly between Twitch.tv and the Overcharge Twitch Enhancement Suite. Can be configured to automatically redirect Twitch links to the Overcharge.tv website, otherwise acts as a quick access button to launch the current stream in the Overcharge app.
A new release is planned that will allow you to view all streams currently online (organized by game) as well as deeper integration with the Overcharge.tv application.
