Well, I guess it makes it easier visually for the programmer. Every command and variable is now laid out neatly line by line in the macro box, rather than having to hit the tabs to see what the commands might be for the various states.

And yes, a hidden device page is always a good idea. I have mine on a 3 sec press and hold on the ENT button on the bottom right of each remote, not only for the devices for the particular room or zone that a specific remote is for, but for every device in the house. Comes in handy when one of the kids misplaces his or her remote. I just grab the nearest available remote and control whatever needs to be controlled.
