It should be an OPTION to have CANVAS override the (in my case, carefully specified) names of the students' submitted files, when I come to download them. (They are computer m-files; I need to run them through a program that depends on the naming convention). What should be a simple "download" becomes hours of additional programming and general messing around, to undo this. A simple email attachment down-loader does the job far better, but oh no, my organisation  has bought into this second-rate ILE, and insists on its use. What a waste of time.
