This very simple module adds a checkbox to the menu item edit form and allows the admin to add html to the menu item title. The idea is to use this for external links for which you want to display a logo of the visited site or simply to add strong on some words.
Note: If you use this module make sure that only trusted users have permission to edit menu items untilis fixed.
This module was created for the KOMA-Script Documentation Project.
The maintainer can be contacted for paid customizations of this module as well as Drupal consulting and development.
