As a Commons administrator, I often have to change the visibility old file revisions for a file because of copyright or other problems. For each revision, I have to click a link, select the correct settings, and input the reason. This is fine for one or two revisions, but when multiple revisions are involved (1 2), it gets very tedious fast. This increases the chance for mistakes and adds unnecessary entries to the deletion log.
In contrast, text revisions have checkboxes that can be used to change the visibility of multiple revisions at the same time. It would be very helpful to have a similar system for file revisions.
