Hi,
I also tend to setup too many scenarios and then my wife and kids keep asking what are they doing....
Then I try to remember that "there's something wrong if menu system has more than X choices on each level"... I usually try to use rooms not just in physical, but also in logical meaning (for instance I have an House Audio room, and all things regarding our house audio channel are there)....
Anyway, we're all probably now in phase where we get all possible commands at our hands on Orbiters... Next stage (far away) would be to make system more intelligent, so majority of actions are taken automatically - that scares some people, but when it will come, it will be usable....
Regards,
Bulek.
