2007-01-18: Version 1.1 is here. Read more about it in the upgrade log. So be sure to download the headerman1.1.zip file!
The download contains the control - and the test website in one single solution (VS 2005 and C#) is used.
Please feel free to try it out - at least for me it has become an invaluable tool as I am actually starting to care a more and more about the HTML layout.
