Front Plus extends the Front Page module. It seeks to make it easier for a non-technical website owner to easily select a front page from a set of pluggable options. This allows developers the ability to create commonly used front page plugins that can be selected by the site owner from a visual list, making the process of setting a front page more straightforward and intuitive for people that are not as well-versed in Drupal.
