I'm a left-hander, and I find that using a Wacom tablet with Lightroom is incredibly cumbersome at times. This is due to the fact that all of the develop panels are on the right side of the screen, and accessing them with my pen means crossing my arm all the way across my body to the right so that the pen can access the sliders on the right panel. My idea is to add a "left-handed mode" that would simply swap the location of the left/right panels, making it easier to access the develop (and other currently-right-sided) panels when using a pen tablet.
