There are several options you van use with the two shortcodes. Here are the defaults for ‘thisorthat':'posttype' => 'this-or-that'
'taxonomy' => 'thisorthat_category'
'category' => ''
'thumb_size' => 'large'
'show_image' => 'true'
'show_title' => 'true'
'show_excerpt' => 'false'
'show_score' => 'false'
The shortcode ‘thisorthat_ranking’ has the same options, but has one added to adjust the amount of items to be shown:'length' => '10'
