I would like to see the ability to create groups to organize alerts. At the group level is where you set the variable like IP Range, and email address to be propagated to the child alerts. Maybe when alerts are added to the group there is another tab that is added that has the values of the alerts in it.
It might also be nice to have trigger action and be able to say if range 10.1.X.X email this group of people, and 10.2.X.X email this to a different set of people.
