Hi,

on config.py exist this function
def addNotifier(self, notifier, initial_call = True, immediate_feedback = True, call_on_save_or_cancel = False)
If immediate_feedback is left to True adds a notifier to self.__notifiers []
otherwise adds a notifier to self.__notifiers_final []

the problem arises when you want to delete the notification
in the first case, no problem, there is def removeNotifier (self, notifier)
but the function to delete a notifier of type __ notifiers_final is missing.

Is not possible to remove a __notifiers_final
