It varies. Things like keyboard control or that kind of thing, absolutely, but mostly I've used it for stuff like "don't make an animated transition every time I change pages like an overcaffienated George Lucas" or "actually make night shift shift enough to be useful at night". I also use the background sounds to augment noise cancellation while taking a nap. All of those are just useful things or personal settings, not necessarily attack vectors.
