This is what we need in 5.1. A way to 'quick reply' with text messages/iMessage. It would be cool if the Notification bar at the top pops up, You click on it, Then a small bubble appears in the middle of your screen. 'Enter your Reply here.' Tap it Bar once to be sent to the Message app, Twice for quick reply. Vice Versa. Also, If you pull down notification center, It shows you the recent text. Tap the text to open Quick Reply. It could look something like Siri's text box. My ideas. Would love for apple to implement this. This way, You can still send texts while in a different App.
