The first thing you notice when launching the app is that it is a bit brighter than before. They have kept the green theme of the interface, but have lightended the background and use the darker green for the banner at the top. This is where it gets interesting. You are initially brought into the Activity screen where you can see the normal status of all of your friends. But then you notice little bubbles next to each status update. By tapping on the bubble you are now able to dive into the check-in and add comments!
