BCM upgrades/additions

I'm going to the dealership later this afternoon to have my key fob problem worked out. While I'm there and the Tech 2 tool is on, I figured I'd have him turn on a few options I don't have, ie. Retained Accessory Power. I have a base model truck, but it'd be cool to add some features. Is there anything else worth activating? Maybe for a later addition item? There's nothing I can think of off the top of my head.
