I typically organize files by class. For example hw1.pdf is class dependent. Rather than storing all of the files in a flat directory, organization by class would be very helpful. Also, when updating files, please allow for a replace function. Currently we have to go to home, delete the file, then back into the assignment page to upload the new file.
