In the PAGES
section you can manage your web pages.
In the first section (PAGES) you can see lists of generic pages of your website. The MAIN PAGES list exists for better organization purposes.
In the following sections before the last one, you can manage the page templates for your item groups. Each item group needs an Item page template and a List template. The Item page template is the page on which each individual item will be presented, and the List template is the page for the lists of item categories.
The last tab is the TEMPLATES tab. Here you can see a list of the theme template pages, and lists for your saved pages and blocks.
