// NOTE: Use of setTimeout
// We're using setTimeout just to make the user experience a little
// nicer, as if we're doing something inbetween steps, so that it
// is a smooth rather than jerky experience.
// >= 300ms is long enough to become distracted and change focus (a full blink, time for an idea to form as a thought)
// <= 100ms is shorter than normal human reaction time (ability to place events chronologically, which happened first)
// ~ 150-250ms is the sweet spot for most humans (long enough to notice change and not be jarred, but stay on task)
