When it works, it's amazing. But on half of the videos, it just doesn't work. The UI buttons are gone, ctrl + wheel no longer changing the video playback speed - The only functioning thing is the custom theme color I set. Replicating this issue may have to do with "Place controls within the video player" but I'm not sure. Could be a conflict with another extension? If there is a way to fix this, I will change the review to 5 stars.
