I wrote a new version of this to use the new log formatting and to include stats on flurry. It only plays a sound on a new attack (ie. a melee hit that isn't a double attack or flurry). Its based on this plugin but only some copy/pasting

It will probably still double-beep for dual wield peeps though. Oh, it also works with importing.
If anyone wants a copy PM me your email address or something. I don't have anywhere to host it.
