I have a suggestion. How about each rule registers itself as a different Growl notification? i.e. when you go to growl, then click Applications, Hazel, then notification, you will realize that all notifications are registered as "Custom" Notifications". Instead, how about each rule has its own category?
This will be helpful if you want to customize the output of each rule into a different notification style. I personally have a few rules that I use Hazel+Growl with, and I get Growl to send the notifications as a push-notification to my iPhone. I don't really care about all the output of these rules since I'm only interested in a few of them but with the current setup, I get everything anyway.
Could you please do that?
