"ON" - Very Cool app but I need help with one thing...

[Mr. B]

So I downloaded this app "On - smarter address book" which is really cool it combines a facebook stream, messaging and a "my circle". My problem is that it does not have a notification for the SMS messages instead it uses the standard messaging apps SMS notifications. When there are multiple messages it prompts which app I want to use however, when there is only one message and it displays their name it takes me back to the original messaging service. Does anyone know of how I could resolve this. I thought there might be an application that would just be a notification app but it seems that most messaging applications include it. Any Help is greatly appreciated !
