I'm not sure if this is a bug or intended behaviour but I found it confusing.
In Gravity Forms 1.7.2 when editing notification in the admin, if I then decide to switch to a different form it shows a blank notification form. I would expect it to default to showing the list of notifications for that form.
This behaviour can be achieved by ensuring when a Form is selected from the Switch Form menu, it removes the 'nid' parameter from the URL.
