It's not working properly.
Try an app that reads mouse wheel scrolling like radiotray-ng and you'll see the custom indicators get vanished as soon as you scroll on it (so as to adjust the volume).
At first the indicators get shown. When scrolling on an indicator, all indicators are destroyed.
Simply killing wingpanel doesn't bring them back, restarting the whole machine does.
