If your site has more pages than you can fit on the navigation bar, the system will automatically create a More link and add all of your new pages as subpages of this More link. This works reasonably well, but a better option is to avoid this More link entirely by making any excess pages of your site sub-pages of other pages. This gives you more control over the structure of the site.
This is managed under the Pages tab. In the site menu on the left of the screen, you'll see a hierarchical tree showing the structure of all pages - any page indented under another is a "subpage" of the one above it, and will appear on the navigation as such.
Drag a page underneath and to the right of another page in the list to create a subpage.
