The best YouTube extension after Enhancer for YouTube™. The filter toggles on the Subscriptions page are probably my favorite feature. The next feature I would like to see is searching through videos in all my subscriptions for a keyword/string. It's quite slow when adding filters on the Subscriptions page and I'd love an option to play every video in a specific category in order of upload date (from user specified date to current date). Still one of the best extensions on the market.
