The ability to have any number of notifications is great.
What would be very nice would be to have the ability to turn on or off each notification selectively. I realize that you can just delete a notification, and then recreate it again when you need it later. But this is a bit cumbersome to manage, and it would be very convenient to be able to activate or deactivate them as they are needed or desired.
Gravity Forms rocks! Keep up the great work!
