Rated 4 out of 5 stars

Great work, the growl notifications are much much better than the stock TB notifications.
<br>Would love to see more options like: open email in main window, filters, first X characters of message body. But still, very useful addon.
<br>Update: More often than not when I click an alert the associated email/rss item does not open, nothing happens or sometimes a blank window opens. If this was fixed I'd give it 5 stars.
