 We need a proper action to add new customs options (button, link,
 information) before and after the "Add New" button  of post pages.
 Such as http://stackoverflow.com/questions/29811433/wordpress-add-custom-
 button-on-post-type-list-page

 on #wp-admin/edit.php line 281
 on #wp-admin/edit-form-advanced.php line 395

 This is just a addition of actions to make wordpress more customizable and
 modular.

 Few use-case scenarios

 '''Solution'''
 We can use the following sample code to solve the problem.

 {{{#!php

 /**
  * Fires before the Add New button is added to screen.
  *
  * The before_add_new- hook fires in a number of contexts.
  *
  * The dynamic portion of the hook name, `$pagenow`, is a global variable
  * referring to the filename of the current page, such as 'edit.php',
  * 'post.php' etc. A complete hook for the latter would be
  * 'before_add_new-post.php'.
  */
 do_action('before_add_new-'.$pagenow);
 if ( current_user_can( $post_type_object->cap->create_posts ) )
         echo ' <a href="' . esc_url( admin_url( $post_new_file ) ) . '"
 class="add-new-h2">' . esc_html( $post_type_object->labels->add_new ) .
 '</a>';
 /**
  * Fires after the Add New button is added to screen.
  *
  * The after_add_new- hook fires in a number of contexts.
  *

 do_action('after_add_new-'.$pagenow);
