The TripIt travel itinerary app has received an update that makes it significantly more useful during bouts of intermittent Internet connectivity. Version 3.6 brings in the ability to make edits while offline. The app will then sync changes automatically once you reconnect.
This feature tops the change log, but it's not what TripIt highlighted when I fired up the app. No, that was the new Enhanced Point Tracker feature that will notify you whenever your rewards points are about to expire.
