Blocks: Course overview plus
Course Overview Plus has not been updated to reflect changes to the core course overview in Moodle 2.4 onwards. Course Overview Campus is an enhanced version of this plugin that is supported for the latest version of Moodle and is available at https://moodle.org/plugins/view.php?plugin=block_course_overview_campus
Example course filters (by the year the course starts in, the lowest level category the course it is and by users holding the teacher role) are now provided. These can be used as templates, feel free to get in touch if more help is needed.
