Persistent desktop notification?

Add-ons Development

Do we have a persistant desktop notification API? Which stick till user dimisses it?

nsIAlertSerivice notifications only last 4 seconds. If i fake persistance with this, i listen to callback on close, and if it wasnt closed due to user click then i re-post that notification which is annoying as its confusing, as the fade out and fade in a of new notif happens and worst of all position can change if multiple notifs are present.

There is notification box Alerts and Notifications
