Publisher includes draft publish previews. When saving an entry as a draft you will be redirected to the default ExpressionEngine entry preview page, which is normally not very helpful. With draft previews enabled, the entry you published will be viewable within the context of your site. Structure managed pages are handled automatically, but additional configuration may be required to view non-Structure managed entries, or entries that may appear only within a listing of other entries. To manage these previews Publisher has a Preview Templates settings page where you can select a template to use as the preview template. You can optionally append the new
url_title, or custom segments to the end of the preview template, thus enabling custom preview templates. This is designed to require minimal to no changes in your templates to preview drafts.
