By default, the widget generates an unordered list of permanent links to blog posts with the post title. The product listing ul has a class of <code>wpec-history</code>.
Coming in future versions is the following…
<ul>
<li>Support for post thumbnails</li>
<li>Support for logged out users</li>
<li>Dashboard for tracking what products your users have looked at.</li>
<li>Hooks and Filters (dependent on user feedback. I can’t really see a need for them right now as the plugin is quite simplistic).</li>
<li>Default styling.</li>
</ul>
