Google Analyticator does add the code. I am talking about general verification of Google Analytics for WordPress plugin.
Due to the API change things have stopped working. Now only manual option is good.
I loved Analyticator plugin as it had stats widget in the dashboard. The developer of it has announced that he would not longer support the plugin or further develop it.
I have already began creating my own plugin as my clients really liked the dashboard stats since most don't want to login to Google analytics.
I am not great in PHP, so I guess it would take me a month or more to first create a test plugin.
