How do you display all the tpl.php template files that are being loaded on the current page?
the only thing that comes to mind is to uncomment $conf['theme_debug'] = TRUE; in setting.php. The description for this setting pasted below. 


  Theme debugging:
  When debugging is enabled:
  -- The markup of each template is surrounded by HTML comments that contain   theming information, such as template file name suggestions.
  
  -- Note that this debugging markup will cause automated tests that directly check rendered HTML to fail.    For more information about
  debugging theme templates, see 
  https://www.drupal.org/node/223440#theme-debug.
  
  Not recommended in production environments.


If anyone knows of a better way - please share.
