Add in a slate notification when a gamepad's state changes in the editor, which displays the Platform User, Device ID, and connection state. In the future I'd like to make a small window that shows you all currently connected devices and the data associated with them, as well possiblly as visualize some of their input or allow you to inject input to different pads.
