Feature requests

I wanted to suggest modifying the plugin with these features. I am not a pro, so if you belive this is wrong, I would apreciate learning about it. It’s just that I believe the plugin would be safer if you update it to:

-insert a blank index.php file in the plugin folder.
-insert defined(‘ABSPATH’) or die(‘Cannot access pages directly.’);
-modify the line: update_option( ‘pc_robotstxt’, $options );
to include sanitation:
sanitize_text_field(update_option( ‘pc_robotstxt’, $options ));

Big respect for your work, I really like the plugin.
Cheers
