Not sure if it’s helpful for you or anyone else, but I wanted to hide this stuff from Editors too.
I ended up modifying the code from @nathaningram in this post to also hide the re-ordering options and clean up the menu a little.
Simply open up the functions.php for your child theme and paste in the following:
// Hides WP Help Functions for Non-Admins
function ni_hide_wphelp_actions() {
echo '<style type="text/css">
#cws-wp-help-actions {display:none !important;}
#cws-wp-help-document .post-edit-link {display:none !important;}
#cws-wp-help-listing-wrap .sort-handle.ui-sortable-handle {display:none !important;}
#cws-wp-help-listing ul { margin:10px 0 0 0 !important;}
</style>';
}
if ( ! current_user_can('administrator') ) {
add_action('admin_head', 'ni_hide_wphelp_actions');
}
