I am not seeing it at all.
I'm sorry, maybe I wasn't clear about that. There isn't an "option" to move menus to the other side of the screen, per se. Instead, using the advanced option, you have to manually redesign the web layout of your site to move it over to the other side.
However, re-evaluating the situation, the request to move menus to the other side is pretty overwhelming and it'd be very "Blizzardly" or "Microsoftish" of me to ignore that.
Given that, I'm going to prioritize "moving menus to the right side".
