A quick - but somewhat unnecessary - comment. Why unecessary, you ask? Because we all know very well that this little app is absolutely perfect. It's implementation into Mail.app is flawless, its functionality brilliant, and its aesthetics unparalleled.
Perfect, that is, except for its lack of Tiger compatability. I would be remiss if i didn't mention how OFTEN i use this app, and how crucial - however sad that is - it has become to my daily work habits. Thus, i am deeply saddened that i must live without it in Tiger. Yes, i know the developer is hard at work on an update, but let me be the first one to how EXTREMELY EAGER I am to see this again in Tiger. Growl is nice, but it's nothing like this.
