I am currently creating a site for a customer. He decided to use Document Center template. We started to build this site and created initial structure. Then I decided that quick launch would be useful so I went to customize its look and feel. To my amazement there was no option to customize navigation on the site settings page.
The problem here is: Document Center template does not have this feature. Since we already did some customization on the site I did not want to go back and create a new site. Here is a simple workaround for this problem:
To customize Navigation simply go to: http:///_layouts/AreaNavigationSettings.aspx
Another question, very similar to this one bothers me: I have a site that is based on the News template. I want to create a blog on the home page. I would like to use all the fancy features of Blog site template on home page. I cannot replace current site since it has a lot of content. What can I do?
