You have to redesign the function q_list($q_list).
It's easier said than done because q_list function links to q_list_items function, which links to q_list_item function, which links to q_item_stats, q_item_main and q_item_clear functions. q_item_main function links view_count, q_item_title, q_item_content, post_avatar_meta, post_tags, q_item_buttons functions. And so on so forth because it doesn't stop there.
But you can edit any of those functions and insert your comment/answer links, especially when you use basic theme which display only question title on the question lists.
To show the answer and comment buttons, you can try adding this function
$this->q_view_buttons($q_view);
to one of those functions. I suggest you can try modifying like this:
public function q_list_item($q_item)
{
$this->output('<div class="qa-q-list-item' . rtrim(' ' . @$q_item['classes']) . '" ' . @$q_item['tags'] . '>');
$this->q_item_stats($q_item);
$this->q_item_main($q_item);
$this->q_view_buttons($q_item);
$this->q_item_clear();
$this->output('</div> <!-- END qa-q-list-item -->', '');
}
If it doesn't work, you need to manually create such buttons that may function as if they are real ones.
