NOTE: On mobile devices there is also a link at the bottom of each page where any columns would be displayed
"show/hide columns on this page"
Taping on that link will turn the columns on for that single page. If you navigate away from that page, or refresh it, or tap on the link again, the columns will slide away and be hidden again. This link allows the columns to be accessible from whatever device you're using.
Though, displaying the columns will push the information off the screen, since now there is not enough real estate on the screen to show the page content, plus the columns.
