Add more debug vars

Hi everyone, I've just subscribed to the dev list, I've been using SMARTY since about a year ago. I was wondering if there is any way to assign more vars to the debug section in some way that they're not included in the general vars section of the console (I need to includ $_GET, $_POST, $_COOKIE and some sql debug). Also I'd need to know wich templates are cached and wich not. I've been searching in the dev list but I didn't found what I was looking for. Is there any method such as assign_debug_var or something similar? Thanks in advance Jose
