I'd like to create a sitemap to plan a future site, and I'm looking for a tool to do it. I'd like to create a list of all articles first. Then a hierachy. Then I'd like to put the articles on several places in the hierachy. I should be able to put one article at different places. I'd like to have the ability to mark the articles in different colors whether they should come into the first version of the website or later.
