While replacing my custom code changes i noticed that it does not appear that any of these have been applied to 1.6 as it was suggested they might be when i wrote those.

It is not a problem i know you only had time to do so much, but i noticed that you actually commented out the keyword section of the code in 1.6 and i am curious as to why? 

In 1.6 in core/application.php  it looks like this

      /* if ( $document->getKeywords() === null )
          {
          $document->setKeywords($language->text('nav', 'page_default_keywords'));
          } */

Is there a particular reason is has been commented out, has the process been moved and improved. 

Please advise on the current standings of these three items...

As far as i can see so far, and i could be wrong. It does not appear that the keywords function is called anyone else that would perform this task.  I am just asking for the current status and the outlook of this is all.

Thanks
