As you are reviewing this (I've suggested something similar in the past), I would like to see a "DEFAULT" setting that could be set with three options so that instead of only pleasing 50% of your customers, you could could please them all...
Option one: Default ON (still can turn it off if needed using the control)
Option two: Default OFF (still can turn it on if needed using the control)
Option three: Default = Last setting. (if it was on last, it starts on, if it was off last, it starts off) (still change on/off with control)
