first, thanks again for adding the function to include a thumbnail! My question is two-fold:
1. What markup is generated for the list of related posts? Is it an h4 for title, such as CategoryName, and then a ul with li items? I ask because we need to visually separate each list of posts by category or taxonomy, and if everything is in an li only, that will be a challenge.
2. We want to show separate lists of posts by Taxonomy 1, Taxonomy 2, and then posts by Category A. How can we do that? Can we add the widget 2 separate times?
