@powelski What about directly adding styling to the input, instead of assigning a class and styling that class, something like this:
```js
jQuery(function($){
  var hightlight;
  if ( highlight = window.location.hash.match(/wp_stream_highlight:(.*)/) ) {
    $(':input[name=' + highlight + ']').css('background', '#ff8');
  }
});
```
And having clickable URLs be like : `wp-admin/options.php?page=general#wp_stream_highlight:some_field_name`
