In modules I indent assignments that build off of each other. I recently learned that this does not lock the assignment until the above has been completed. The only way to do this is through the "must complete in sequential order" option within module settings. I am sure that 8 out of 10 times that is fine. But sometimes I will have two concurrent assignments in a module and students could choose to start from either one to complete the steps to finish up with the topic.
Indenting to lock an assignment until the above assignment is completed is an easy way to intuitively lock assignments to be completed in order without blocking out other options and pages within a module if not all items need to be completed in sequential order.
