Only change - Added up to 2 venues to your main activity tab that you are most likely to be checking in to.
The algorithm for this was built overnight so I apologize if this version is buggier than the previous version.
If you don't want to set the predicted location as a favorite you can use the options menu on the edit settings page to directly check-in to that spot.
