Address Book has some neat built-in features. Some are more hidden than others. Most people find that by clicking on addresses, a menu will pop up offering to bring up a map for that address. Very cool. What is not cool is that it uses MapQuest.
Not only will it bring up addresses in Google Maps, but it will also assist in finding directions between any two entries or custom addresses you write in.
It even sports its own preferences, allowing for customizations that will assist in making the address shown more accurate (by blocking out apartment numbers and the like). If you enjoy Brian’s terrific work, let him know with a donation.
