Did Exactly what dev promised on a very specific website and application (notably v4c.fun). Your mileage may vary but on this website does exactly what it should do.

It sort of works, but it only restores the layout and not functionality. If that's all you need, grab this extension! If you want functionality back you should know that these are still not working:
- double click for full screen
- scroll volume bar
- < and > for speed down/up
- left/right is still -/+10s in stead of 5
- up/down doesn't change volume
- 0-9 buttons don't jump to 0-90% of the video

works half the time
