By default the Shopp breadcrumb will display “the path you followed to get here”. And frankly, that is 
what breadcrumbs are meant to do. However this means when someone enters one of your product pages using 
a direct link, the breadcrumb will be empty. It will just show the link back to the main Shopp page. 
With this plugin installed you can use breadcrumbs that show “where you are” in the hierarchical 
structure of categories.

Ever wanted your users to see all the pages that they have previously visited. Well now you can!
Here’s how it works:
The value of the current url and an appropriate title of the page are stored in the users cookie. 
As the user browses the site more the number of links stored grows.
<a href="https://codex.wordpress.org/Shortcode_API" title="WordPress shortcode" rel="nofollow ugc">shortcode</a>
You can place the ‘[history-tracker size =”5″ order=”oldest”]’ shorcode into any page or post or 
If order attribute is set to olderst the order will be reversed. 
There is no description or title attribute.

History Tracker

Tracks the history the users visit and displays it to them, like the browser history but only for your website
