Additional Restriction before Count

Please, add additional restriction to plugin options before count.
Might not only I, always have to update code manually every time plugin get update.
For me it is important:
– not count if author view his own post
– count only published post, and not count pending or when preview from admin
– restrict count only for specific roles, one or multiple
For example, line 118 of wp-postviews.php:

if( $post->post_author != $user_ID && $post->post_status == 'publish' && !current_user_can( 'upload_files' ) &&
… or selected roles in array, than update_post_meta ..

Keep developing. Thanks!
