... Some audible indication if you receive bitcoins. Andreas Schilbach's wallet has a very neat 'tinkling coins' sound. Just something subtle. Would be a great addition in the user experience, I think (sounds crazy, but often I've heard "damn I love that sound of incoming coins!")...
Agreed, weren't the devs talking about not being able to add notifications though? I would really, really like to be able to receive push notifications/have a sound when coins are received.
