In new simplicity skin there is no notification from the panel as to whether an event was successful or not.
in the upper left corner have a div z-index above all else, position absolute, top 10, left 10. When ever you do an action display a message in this div set a timer, 5 seconds, hide the div.
It would be different, and look professional.
Just a suggestion. It is nice to know the status of an action.
