By default, the front page shows Section names and their Contents, as well as thumbnails with named Contents. The Layout Tool lets you change the look of the Section pages, but for more layout control, you can manipulate the variables directly.
The Contents-elements Variable controls which parts of your pages are displayed. These include: Image, Bullet, Screen-text-title, Display-text-title, Abstract, Caption, Price, Order, and Contents. Hold down the "Ctrl" key to highlight two or more selections that are not consecutively placed.
You can override the Contents-elements on any individual page. In fact, that is what the Layout Tool does.
You may want to change the value of the Columns field if you change the Contents-elements.
