It's a great addon. I would like to make a feature request as well while I'm at it. Would it be possible to allow for ignoring certain folders? The reason I ask is I currently have Thunderbird set to automatically save a draft each minute. This means the addon will Growl every minute as well, since a new message appeared in the Drafts folder. The same is true for the Sent Items folder when I send an email. I would like to ignore both these folders so I only get Growls from mails I receive.
