You can override how this page is sorted when displayed within a category by setting a different index to sort with instead. This is often used to make pages about people show by last name, but be named with their first name shown first.
You can prevent this category from showing up in the list of categories on member pages. This is useful for categories that are of interest to editors but not most readers, like pages which need an illustration.
You can force the display of an extra tab besides the "$1" tab on this page which will make it easy to add a new section, or force it to not appear if it otherwise would.
