If you’re not familiar with it, this novel format provides users a different view of a Moodle course by providing a matrix of images (in a grid) which represent each of the course’s topic areas. Clicking on each will open it within the same window as a modal (no page refresh required).
The “release candidate” available to test is available from this link https://moodle.org/plugins/pluginversion.php?id=8532
