Seems like a pretty cool extension, I mainly am trying it out because I dislike YouTube's new, gigantic thumbnails on the home page and subscriptions page. YouTube Redux fixes that problem on the home page, but not in the Subscriptions page as far as I can tell. It *does* reduce the size of the thumbnails, which is nice, but only to a medium size, and there are still only 3 columns. Having that feature work on the Subscriptions page would be awesome, so I hope it is added at some point. On the totally positive side, I'm not seeing ANY shorts thumbnails now, which is fantastic!
