This extension isn't yet perfect, but it makes the Twitch viewing experience FAR better and much more enjoyable! Updates are thoughtful and are made on a regular basis. This is probably just a 4 star extension, but I DON'T HESITATE to give it 5 STARS because there is simply nothing else like it - no other extension competes with "Preview's" tremendous set of features or it's developers commitment to constant improvement. If only Twitch cared as much for their viewers as this developer does!
