Amazing addon and can not stand youtube without it but there is a small problem where recently the things under the video end up blocking some of the player if you set the player to theater mode by default. However, there is a simple fix for this by switching to default view only to re-enable theater mode again after the page has finished loading. If done correctly it should be fixed but you will have to do that with every page till the addon gets fixed. That small issue was not enough to lower the raiting tho since the dev will likley have a fix for it soon and it is not that hard to do the trick above to fix it yourself till then.
