Several times throughout my academic career, I have completed an essay several days before the due date and given a copy to my peers for review. Usually, I use their feedback to fix my essay and then submit it, no problems. But several times I have forgotten to submit my essays because I forget that I never submitted it after revising the assignment.
What could be useful is the ability to configure your account such that you could automatically turn in a certain file at a certain time. What I'm envisioning is picking a document from google drive several days before the deadline, typing and revising my essay, and then continually changing things up until the deadline, allowing for a more natural creative experience.
