Check-out Option. Privacy for Home Address

I have two ideas for you're already awesome service:) 1. It would be great to have a "check-out" option. When I leave a place, I may not get to the next location for a while, and I'd like folks to know that I'm not at the last location anymore. 2. I would like to have an additional level of privacy for my home address. Basically, if I could just have home address be set to always private, but still say "home" that would be awesome.
