I like adding in the Christmas lights too. And Indigo makes it so much easier to create custom schedules than my old "dumb" timers. It's nice to have them run for an hour or so in the morning before the sun comes up, or having the bright tree outside the guest room window cut off early when we have early retiring guests in residence.
I admit I had a bit too much fun last year creating highly realistic CP images of our various over-decorated trees both on and off though...
