With the jQuery version, it was possible to automatically hide notifications after a timeout with the config property autoHideAfter. There was also autoHideAfter, which I need too.
Also, there is a feature request for this in our portal and I can suggest voting for it as it will increase its chances to be implemented as a built-in feature:
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
