You can now hide/show individual activity modules and even delete them completely! For example, if you hide the "choice" module, then all choice activities will be hidden throughout the whole site, and "Choice" will not appear on any "Add..." menu. Deleting a module is a complete deletion of all data from the database. If you want to try out the deletion on a real module, I suggest the pgassignment module, since it will soon be deleted from CVS anyway (because it's being replaced with workshop). Look for "Manage modules" on the admin menu.
