In the "All Documents" page where all the docs are listed, there is a category for "Currently Editing" (Title, Workflow State, Currently Editing, Owner, etc).
Since showing who has checked out a doc is of no concern for my purposes, I created a new Taxonomy title "Locations" which shows which location that doc (or resumes, for this purpose) was uploaded from. I have 5 options like "Atlanta", "Memphis" etc. and would rather show this location selection in its place.
So basically, in the "All Documents" page, the header will show Title, Workflow Status, Location, Owner, and time.
How can I change them out?
