This module is an Extended Tracker module for Drupal. It has all the functions of the core tracker module  (the module  that provides the "recent posts" menu in the navigation block), and adds a few features:

• Ability to restrict the listing to certain taxonomy terms.
• Ability to list node scores (as assigned by the nodevote module)
• Ability to sort on any column (title, author, score, number of comments, last post date, ...etc.)
• Ability to change the number of nodes per page displayed.

The taxonomy feature works well in some themes (e.g. CivicSpace) but not others (Bluemarine). See  the README file that comes with the package for more details.
