On this note, it's annoying that OS X doesn't provide an external per-app volume control like Windows has. For example, Gmail's voice chat doesn't have a volume control; if I'm watching an iTunes video at the same time (along with the person I'm voice chatting with) and want iTunes to be louder than the chat (due to background noise from the latter), the best I can do is turn the iTunes volume up, but setting it to maximum is insufficient. With such a feature, I could just turn down the browser's volume, though I suppose it's still worthwhile to have volume controls directly embedded in video players for convenience.
