This has saved me a lot of hassle with a current website. It took a while to find an extension that did what I want - this one does.
I guess the only thing extra I would like it to do would be to have one long user-orderable list of every article in a section without them listed in their categories. However, this is not a gripe by any means, just a "would like to see" for further versions! Full marks from me - thanks!
