PlaceTrack version 2.3 is coming with a couple of important new features: Auto Check-In and Delayed Sync.

Auto Check-In: Automatically checks you in to your favourite Foursquare or Facebook venues as long as you’re within 15m for at least 4 minutes.

Delayed Sync: stores your locations when you’re offline, push them to your Latitude history when you’re back online.
