Fullscreen mode

Please add a button which will allow us to play in fullscreen. The screen in lichess is too small and I don't enjoy it. We could deactivate it after the game or if anyone doesnt8like to play in fullscreen. I think it is very easy to be done but it would be very usefull!

Just press F11. It should work on most popular browsers.
You can also increase the board size by clicking the theming button and dragging the magnification slider bar or even zooming in through your browser.

What is the theming button? Where is it?

And what if someone plays through a tablet? There is no f11 button there.

There's also an app for certain devices http://en.lichess.org/mobile
