Not very intuitive

Got me quite confused on how to handle it. Would have expected that I could control which contacts to extport. Instead you have to make a Group in your Address Book, open this Tool, change the group in the settings and then finally hit the button. (Oh, and it wont reconize a new Group until you restart the App).
Do not use this to export to GMail!
