Is there a way to forward Growl notifications to Notification Centre?
Since version 2.0, Growl supports "bubbling" notifications to the Notification Center out of the box. You can find the setting for this in the General tab of Growl's preferences.



It does come with the same limitations as Hiss though, all notifications appear to be coming from Growl and not the originating app, and clicking them does not appear to launch the expected actions.
