Restrict Document/Proof Download Ability

[#1]

There is a proof setting to 'Allow downloading of the original file' which for some reason only works when the user is in the proof viewer itself. Anyone on the project the document/proof resides can still hover over it in document details and download the file. This defeats the whole purpose of this proof setting. WF needs a way to restrict who can download a document, if they are not on the proof I don't want them to be able to download it until it is approved!
