I thought I would update this thread since Wayne from Technical support answered me directly. He recommends using the Control Pads to represent the rooms, which keeps everything very neat on the carousel. I originally started to use custom buttons on my HomeTheater screen to fire off Activity based macros (Watch Movie, Watch TV, Use PC) etc, but then found that the Command List function was a bit cleaner. Currently for some reason my macro is not jumping to my preferred screen location as it should at the end of the macro, but I am sure they will sort that out for me. It would be real nice if you could add any of the Control Pad icons to buttons, since if you want to do an activity type of macro, the icons looks a lot more professional then just text. (Ie Watch Movie becomes the film icon). I also was surprised to see that there were no PS3 icons (colored triangle, circle, etc) as you can use the PS3 IR with a third party dongle. All in All I am EXTREMELY happy with the blaster and the ballistically fast assistance from Square Connect technical support. I can't wait for the SQ Designer program and the iPad specific program that will let me take advantage of the much larger screen realestate.
