[Resolved] 3 questions about wp show posts

Three questions:

I have two active snippets and I think that they maybe are outdated?

1. First snippet: add_filter( ‘wpsp_pro_beta_tester’, ‘__return_true’ );?
2. Second: Wp Show Posts Category Pages

add_filter(‘request’, function( array $query_vars ) {
if ( is_admin() ) {
return $query_vars;
}
if ( isset( $query_vars[‘category_name’] ) ) {
$pagename = $query_vars[‘category_name’];
$query_vars = array( ‘pagename’ => “$pagename” );
}
return $query_vars;
} );

3. I would like to show my search results in the way I show my wp show posts category pages. Can I create a search results page with wp show posts? At the moment search results display a little ugly.
