Expand/Shrink right & left columns while Auditing docs

The point of the audit section is to review files. Right now, I can only review docs within the center one-third of the screen and I am not able to shrink the other sections of the screen that are irrelevant as I'm reviewing docs.

Make it so that users can shrink the left column and the right column while in the audit section reviewing docs. That way, the main subject, the actual documents to review, can be much larger on the screen.
