Utilizing the desktop category page style “Boxes with Subcategories” setting I was able to create a Theme Component and add code below the Boxes. I’m now figuring out how to list the latest topics on the whole site.
<script type="text/x-handlebars" data-template-name="/connectors/category-boxes-after-boxes/mwp">
<div class='column'>
{{categories-topic-list topics=topics filter="latest" class="latest-topic-list"}}
</div>
</script>
The problem is that this simple says “You’re all caught up”
