The section manager allows you to see all of the sections you’ve created for your yearbook. You can create new sections, edit pages, rename a section, mark as ready for review, lock/unlock and delete a section from this area.
Clicking on a section name takes you to edit mode for that section which allows you to proceed with your design. Alternatively, you can click "Edit" from the gear icon menu shown above.
Mark as ready for review signifies that a section is complete and needs to be proofed before locking.
Locking a section means the section has been completed, proofed, and ready to go!
Renaming allows you to rename the section.
Lastly, clicking delete allows you to delete a section.
