I originally only got this add-on to be able to watch youtube videos in a larger format than youtube naturally supports, which the "resize player" button does perfectly, but this add-on has so many good things about it. I especially like the ability to speed up or slow videos, which is very useful if I just want to skim a video but not miss things, or if I am looking for something specific and don't want to keep pausing. Additionally, being able to loop videos, and only certain parts of the video, is excellent when I want to listen to a song multiple times and it has an intro/outro I don't want to head. All in all, awesome add-on that I doubt I will ever not use for youtube.
