The Title property defines the text of the heading that is added to the page, and also identifies the User Item in the User Items list.
Page Break Before
If Page Break Before is checked, Gedcom Publisher will add
page-break-before: always to the CSS styles for the Chapter Contents heading. E-book readers that support the
page-break-before property will render the Chapter Contents after a page break.
The Heading Level property determines which HTML element is used to render the heading,
It's usually best to leave the Heading Level set to the default, which is "h2".
