When opening a thread, any Twitch video that has been embedded in the thread will automatically begin playing. You then have to track down each video and pause them. This can get quite annoying, especially if there is more than one video in the thread (they all play over each other.) Furthermore, if you then sort the thread by different parameters (for example, swapping from "top" sorting to "new" sorting) all of those videos re-load, and once again begin playing, forcing you to once again find them all and pause them. It creates a real big mess in any thread where Twitch videos have been linked.
