Gnome-Do Usability: Right Click in Docky

So before using Gnome-Do I was using AWN. In AWN on their bar, you can right click say Firefox and it gives you the option to minimize, maximize, or close. Is there a way to add at least the close option to the right click of icons in Docky? If that is not in there already, do you guys think its a good idea? Maybe have it as an option that the user can check or uncheck depending on their preferences?
