Preview file on back-end

Would it be possible for a future release, that you add the ability to Preview a file on the back-end just as we have on the front-end?

We currently send users to the front-end viewer and our admins to the back-end interface so that they can manage the categories and documents, because the admins will be in the back-end interface more often, it would be a nice addition if they were able to preview the files from there as well.

Thanks,
