Alter Control: You can turn off notifications completely. Now since you have a counter for call and text within the app, you get to know many are unread.
In-App Notifications : This is just like Hike where it shows notifications from other chat thread when you are on different chat thread.
Message Preview : This is when you exit the app, and notifications pop-in. Instead of saying New Whats App Message, you get “Message from XYZ”. The text is not shown though, I would have loved it with option to reply!!
Thanx keshav for this tip!!!
