Widget manager....

 		/*
         * Use a theme or app specific widget ordering list to determine what widgets should be included
         * for each module and in what order and optionally what region of the page to place them.
         * For example:
         * view/wgl/mod_connections.wgl:
         * -----------------------------
         * vcard aside
         * follow aside
         * findpeople rightside
         * collections aside
         *
         * If your widgetlist does not include a widget that is destined for the page, it will not be rendered.
         * You can also use this to change the order of presentation, as they will be presented in the order you specify.
         *
