absolutely fantastic plugin, I have been wanting to do this for a while and I am so glad i have found your plugin! Some times when you make a website for a client they only want basic front-end access, so if they add a new page you want the page to be add to a certain menu automatically. This is exactly what this does!
Will there be a artcats plugin made for Joomla 1.7? I really hope so as a few of my new sites are made with the new Joomla!
