I use growl all the time with itunes or play. It works great but there is something bugging me. When i am listening in random and doing next until i have a song i want to hear(i dont look at the playlist i use hotkeys while i am working), my screen gets invaded by growl notifications. I am sure i am not the only one having this problem, it also happens with mail when i have a lot of new mails.
So i was wondering if it would be doable to add a per application option to have only one notification at a time?
