This has been added in version 1.2.0.
There are a couple of new functions and a shortcode.
The function get_users_who_favorited_post($post_id) returns an array of WP User objects who have liked the post passed in.
The function the_users_who_favorited_post prints out a list of users who have liked the post. There are some options/parameters available to show/hide anonymous users from the list, and formatting. (see the plugin website for full list).
The shortcode [post_favorites] does the same as the print function above. Details and its options are available on the plugin site.
