Comment on MetaGrowler

I like this app and the features built in, but I have some suggestions. I would much rather see it as a preference pane that is hidden away. The menubar icon is somewhat pointless when the only thing it does is quit the application and allow you to open the preferences. (which doesn't allow you to do all that much) And since growl display's the application icon when it notifies something it would be nice with a nice application icon, maybe even different icons for different notifications. If that's possible.
