Edit this template:
xfrm_resource_list_macros
Find this:
<xf:if is="$resource.isDownloadable()">
Add this code above that:
Code:
<dl class="pairs pairs--justified">
<dt>{{ phrase('views') }}</dt>
<dd>{{ max($resource.view_count, $resource.download_count, 1)|number }}</dd>
</dl>
It's better to do it using Template Modification system, so that you don't lose it in future if that template was updated during upgrade.
