it's great that sections can be deleted since Moodle 2.9.
At the moment when clicking on the delete button, a new site is loaded where the security question is presented.
It would be great if this could also be done with AJAX:
When a user clicks on the delete button, a modal window occurs with the security question (Are you sure you want to delete and so on). If he clicks on yes, then the section should be deleted and the GUI should be updated - just the same way as it works with deleting activities or resources.
