Any way to make Ultimate FB widget disappear if user is not logged in to FB.

I am using the Ultimate FB Like Box widget and have found that the box is at 100% and mostly empty when a user is not logged into FB at all. It seems to me that there should be a Like button or maybe the widget should disappear completely if the user is not logged into FB at all. Can you improve the plugin, please? This looks unpleasant if someone does not use FB (though not likely, but I need to include those website visitors).
