That's something I can do. I think adding one parameter can make it work.

"dismissTime" which will allow three kinds of values: 1)a number means the time that the message dismiss(3 seconds by default). 2)"never" that allows to set it never disappear unless user click the "close" button.
(BTW: There might be something wrong with the demo of the close button and it works fine in kimchi.)

Thanks for the sample! It is really good to know how the widget will work =)

About the widget itself: it looks very nice but I have a comment to do.
We've already had some comments regarding the message appears just for some seconds which can not be fully visible to the user.
So I'd like to know if is possible to add a dismiss icon for the notification and only hide it when the user select to dismiss. Otherwise, the message will be always there.

More comments below.
