It would be nice if there was a cool sound that would play when you receive or send BTC.  I love the little "beep" that blockchain.info wallet uses.  It's very helpful as well as nice to hear...the "sound of success".

But even better for Multibit would be if you could choose the sound to play from your PC...wav file or mp3, etc.  It seems like it would be simple to implement (well easy for me to say), but just a suggestion that would be a nice improvement..thanks for the consideration.
