Love this addon - combined with a high quality TTS voice and the speak display for growl new emails are actually announced to me - which it great while I'm working.
A lot of others did notice the limitations of not being able to filter things. This addon also growls before junk filtering so you get lots of notices for things you probably don't want. Maintenance of the addon seems to have stopped so I forked up a github and added some of these features. Hopefully It's ok to share that here for anyone that wants it:
