It would be really great if there was a way you could grant either, a "download" access level, where only certain users can download files.
Or, a way in that only approved files could be downloaded from a review, rather than all files that might not be approved.
In my teams case, users tend to open up the approval view and approve a couple of files, and use the arrows to flick through other files in the review. We find that users end up downloading files that are not approved, and don't realise.
It'd be more useful as an option that we could control based on access levels, rather than a flat rule for all.
