My first question is what is the difference between the following states: visited, down, disabled, and selected? I see that selected and down behave the same, but the functionality of these four seem to be very similar.
I would also like some advice on a project we're doing. We're using the iPad template that we downloaded from here, but we are modifying it a bit. We have several buttons that have three triggers: 1. show a layer when hovered over, 2. go to a slide when clicked, and 3. change the button's state when clicked. The user will need go back to this home page after visiting each button. Also, we have a "final layer" that is triggered when the state of all the buttons are "visited." However, when you hover over a button in the visited state, the final layer disappears. How can we prevent the hovered layers from coming up after the button has been visited?
