Great Extension. I wanted to add Growl notifications for specific emails,After some searching, I ended up using 'FiltaQuilla' to filter and launch GrowlNotify for specific emails. (http://www.growlforwindows.com/gfw/help/growlnotify.aspx).
Only issue I have is that I cant pass any customDBHeaters to GrowlNotify for some reason.
