It would be nice if I could setup which contexts were available in specific places, and then GPS could automatically select which contexts are currently available to me. For example, if I could setup a place called "Home" where the contexts "Phone, Internet, Wife, and Home" were always available, and then those contexts would automatically be selected when OmniFocus determined that I was at the "Home" location. Likewise, I could setup other places that I frequent (work, airports, hotels, in-law's house, etc) and the relevant contexts could automatically be selected when I was there as well.
