Overall great
Easy to use, and sounds are good. I agree with adding some "coffee shop" type sounds. And one other thing: it would be nice to have easy keyboard shortcuts to turn off/on the sound (and maybe even to change sounds). I find that when I get a call, I just mute the computer, but then I forget Chill is running until later, and its unnecessarily using up computing power (as well as surprising me later when I wake the computer up and it starts making noise!).
