Big Libraries that consist of many fields may embarrass the end user. To make the structure logical and easy, we advise you to divide the content into pages and subheaders.
By default, there is one page — Main, but you can add as many as you need and set the one as a default. To create a new page, click the button at the bottom-right of the window and choose the relevant option from the list. Enter the page name and click OK. Later, you will be able to Set it as the default one, Rename, move Up or Down among other pages or Delete it.
