It's a decent application. The interface is kind of basic and the application's functions are very basic, but it has potential.
There is a bug, though. Start up iChatState and then click the red x in the corner to close the application. There's currently no way of re-opening or opening a new instance of the application. You'd have to quit the application for it to show the GUI again.
Otherwise, it's a decent app and does as described.
