I see that in Moodle 2.4, the "revert to draft" button is no longer there. I use this all the time. With over 200 students in over 5 different courses with 40 assignments in each course, it's extremely time-consuming to now have to go to the course, to the assignment, to "view grades", find the student , and then click on the edit button. This is a step backwards. I like to give my students the option to revise work once for a better mark, so clicking on "revert to draft" is key.

Please bring this feature back!!!
