-Platon has some new features
The tile menu to the left is know linkable to a Drupal menu.
Under the Platon theme settings, you may choose which menu to render.
The left column is collapsible.
A cookie stores the state so the menu remains collapsed when navigating the site.

-Fixed the bug with the Course Catalog.
