This is in aid of providing the user with more feedback about the program (eyes and ears) than the light readings and web requests. The toggle button allows the user to turn-off the logs if they don't want or need them. This is not a full implementation of the logging system (this is just a start).
The logic for 'factory3' and 'gallery3' is still in place but is not bound to the view (MainPage.xml). The view xml is commented out and not removed. This should make it easier to re-add it if the need comes about.
