I had a look at the code to see if this could be easily implemented, but it would quickly complicate the plugin. My intention was to add an option that if checked would show the widget only if current_user_can( 'edit_theme_options' )
returned true.
But a hall pass has already been given to the Front Page logic; adding another exception for status of user makes the logic difficult to follow.
It does seem like this is best left to another plugin.
