Role based notification settings
it would be nice to have some sort of role based notification settings. Background is: I would like customers to only get notifications if the issue gets assigned to them. If there's all kinds of action, like document adding, message adding etc etc, I don't want the customer to be notified.
Also, only a message that is being added when the issue is being assigned to them, or while the issue is already assigned to them, should be mailed to him.
Any ideas anyone?
