It would be useful to show the student details of the file they're uploading (for example, modification date is useful to confirm they're uploading the most recent version). We do actually see a fairly large number of mis-uploads with the existing upload system, and are hoping exposing more information during the upload (rather than once the file is received) will help.

I was just going to ask the same question.  My use case is for a progress bar.  As I parse a file, it would be nice to have a progress bar based upon the file size and how much has been parsed.
