Save user’s favorite posts and list them. 
This plugin is simple. You can save the user’s favorite posts just a install and display them anywhere you want with just a shortcode. 
The logged-in user’s data is saved in the user meta. Other user’s data is saved to Web Storage (localStorage).
<h3>Usage</h3>
<ul>
<li>Shortcode: <code>[ccc_my_favorite_select_button post_id="" style=""]</code></li>
<li>Shortcode: <code>[ccc_my_favorite_list_menu slug="" text="" style=""]</code></li>
<li>Shortcode: <code>[ccc_my_favorite_list_results class="" style=""]</code></li>
</ul>
For pages with a shortcode for list view ([ccc_my_favorite_list_results]).
“Load More” is displayed with “posts_per_page”. 
It will be displayed when the user has more favorite posts than “posts_per_page”.
<ul>
<li>Shortcode: <code>[ccc_my_favorite_list_results posts_per_page="10"]</code> default is 100 posts.</li>
</ul>
You can display the post’s “excerpt”. 
This value is the char length. 
If not needed, use “no excerpt” or “0”.
<ul>
<li>Shortcode: <code>[ccc_my_favorite_list_results excerpt="30"]</code></li>
</ul>
If you want, you can change the code for list view yourself.
<ul>
<li>Shortcode: <code>[ccc_my_favorite_list_custom_template style=""]</code></li>
</ul>
For pages with a shortcode for custom list view ([ccc_my_favorite_list_custom_template]). 
Add the function (<code>function ccc_my_favorite_list_custom_template( $my_favorite_post_id ) { }</code>) for your list view to <code>your-theme/functions.php</code>. 
 $my_favorite_post_id is array. 
 style=”none” excludes the default CSS for the list.
Detailed usage is under preparation.
