This is strange:
Your plugin is working fine in my sidebar, but when I try to use the shortcode, it doesn't register all the parameters.
"Orderby" and "pformat" work fine, for instance, but "count" does not—it always displays all the posts of the selected type, no matter the value. Since I'm querying a CPT with 3,000+ posts, displaying all of them is out of the question.
Thanks, by the way. This plugin was just what I was looking for.
