Many teachers are interested in using modules, however, the extra step to add assignments to modules after creating is just "one more thing to do." If you start from modules and add assignments, it feels disconnected and clunky. Everything else is available from assignment creation: due dates, grades, submission options, files. Ideally, there would be a checkbox in the assignment "add to a module" with a pull-down menu of previously created modules. Later teachers could organize the content if they needed to do so. This would make module use a better integrated overall experience.
