I created a role in wordpress where a specific user can see the backend file manager of WP File Download in order to manage the repository of files. In a middle/big company could be helpful to have more people working on it but they shouldn't be always a webmaster administrator. At the same time there could be an area for high level manager which contains private file that shouldnt be see by everyone, so I'm proposing to add visibility permission also in the backend file manager.
Hope to be clear enough in the explanation.
Thanks, have a nice day!
