Right Sidebar

For navigational consistency, all section navigation is positioned on the left column and all peripheral sidebar information should be placed in the right sidebar.

OmniUpdate users will have an option of displaying their social media icons in the right sidebar instead of the header.  Since the sidebar is optional and formatted to display or hide at the page level you will need to have the sidebar enabled on each page for it to show.  There is no global setting to force the sidebar to show or hide at the site level.
