Configure the Gnome panels from one single application

I propose to create a configuration app, placed in System->Preferences and named "Panels", from where you can configure every panel. The design of the app should be taken by the preexisting gnome-panel-preferences UI.
From this application you could also create and remove panels, thus removing the options "Delete this panel" and "New panel" from the right-click popup menu and leaving the "Properties" one (which launches the general application).
