    appDisplay: Default to All view when not enough usage data is available
    
    The frequent view is not useful when it doesn't contain any applications
    yet. While the previously added label makes this state appear less like
    an error (OMG, my apps are gone!), it doesn't address the issue of
    usefulness - default to the more helpful All view in this case.
