Hi, I am interested in developing a diagnostic theme or method to display phptemplate hooks called in a CSS hover over that element. So when you hover over the breadcrumb HTML output on your website it displays: phptemplate: theme_breadcrumb() called in a CSS hover. and that way the designer knows if he/she wants to modify the breadcrumb they will have to look at the $breadcrumb variable or override theme_breadcrumb. It's kind of like how devel.module helps write modules, except for themes. So far the only idea I have is to intercept _phptemplate_callback [1] but wondering if anybody has any better methods.
