Hi!
If you decided to remove it (and did not simply forget it) in the new UI, that's the most important point.
That's a decision.
Nevertheless, I can hardly imagine that people deliberately REMOVE an application from Growl
and then would complain to have there settings lost for this app ;-) But everything can happen with users ;-)
The best way could be:
- to reintroduce this simple useful button for the user who wants to clean (or reset!) its settings for an app
- and to add a very clear alert telling him he will get the result you mentioned.
Otherwise, manually removing the key would be a solution, not very user-friendly though... and where is it documented? I'm not sure to do it correctly if I dare to.
Best regards,
-Yann.
