Hiding Wordpress Pages from Wordpress Admin (individuals getting certain templates -- via plug-in), the next solution appears to operate pretty much except the Page Count (All Released) still includes the hidden pages. Wondering what action I would hook into to change this site Count output? Here’s the filter I’m using to cover the preferred pages.

    add_filter( 'parse_query', 'exclude_pages_from_admin' );
function exclude_pages_from_admin($query) {
    global $wpdb,$pagenow,$post_type;
    if (is_admin() && $pagenow =='edit.php' && $post_type =='page') {
        $where ="WHERE meta_key = '_wp_page_template' AND meta_value IN ('tpl_products.php','other_products')";
        $result = $wpdb->get_results("SELECT post_id FROM $wpdb->postmeta $where", ARRAY_N);
        foreach($result as $category) @$categories[] = $category[0];
        $query->query_vars['post__not_in'] = $categories;
    }
}
