    Hi, it's me again. I see your code for filtering the wrapper opening and close. However I need to get the category variable into the opening. What is the best way to accomplish what I want without hacking your plugin?

    Below is my hack to your line 149, the results of which provide a link to the category page of the category that was specified in the shortcode [display-posts category="Foo" posts_per_page="3"] and looks like this: Foo Headlines : More Foo

    $open = apply_filters( 'display_posts_shortcode_wrapper_open', '<h2>' . $category . ' Headlines : <a href="' . get_category_link( get_cat_ID( $category ) ) . '">More ' . $category . '</a></h2><' . $wrapper . ' class="display-posts-listing">' );

    Hmm, I don't think that can be done with the filter as it is. All the filter lets you do is modify it as straight text - it doesn't pass any of the shortcode's parameters for you to work with (like category).

    I'd need to modify the filter to pass the $atts, and then you could then pull the category out of that.

    Well, I'll leave it up to you whether you think that would be useful to others and worth your effort.

    p.s. I do appreciate your super clean work, which even I, a novice, can recognize!
