Recently Featured courses block was released in the Moodle plugins directory which enables you to select some courses to be displayed on front page.
For each course, the block will show it’s name with a link to course page, it’s summary and summary files. It is also possible to set sort order.
To select featured courses, add the block to front page, go to edit settings, click on the link on the settings screen. The order of the courses displayed by the block is defined by the “sortorder” field. It is an integer field that the records are ordered by.
