You should be able to browse through previous moves in zen mode

When playing in normal mode you have the history of moves on the side and you can use it to navigate to a previous position if you so wish. That's not the case in zen mode. I understand that hiding the move history might be voluntary to avoid distractions, but I find the impossibility to go back to previous positions rather annoying. Maybe there could be arrows below the board, just as in forum embedded games?

Use the left/right arrow keys on your keyboard.

@ornicar What if I am playing using my phone's browser?
