Hello,
it would be very great if you can add the (Lights Off ) option on player bar.
i see that before in one of players

Thanks

LightsOff effect concerns all of website content and not a player.
It works thanks to javascript, and there are many examples of such code.
So first thing is to have such js code and well coded website's html.
Then calling such javascript is not so big deal using any button somewhere around in html.

We don't plan put a button on player playbar for it for 3 main reasosns:
1. lightoff requires javascript function and it can be different function, depending which one is working on certain website. So the player cannot know which function call.
2. There are so many button on player already that putting another one would not look great, would also be to messy for users.
3. As it's available to put standard lightoff html button (any shape, any place) on website page - there's no big sense to put it on player.
