I'm looking at their App Nap functionality and I am wondering how it will affect applications that do background work. It looks to be on by default unless expressly turned off by the app. Does it apply to all processes or what is their definition of an app? I wouldn't want just anything to be suspended when I don't have it on my screen (any work that I started and am expecting to continue in the background basically).
