WebGUI Customisation by Jesse Kinross-Smith


Additional features of the WebGUI version of Newfangled include:

    * Newfangled Page Style and three-column Newfangled Page
      Layout Template.
    * Custom Asset Templates for a variety of assets, including:
       o Two different article templates (Boxed Style - designed
         for the side columns and Post Style designed for the
         middle column) - this adds funky rounding on the corners
         depending on which column it's in.
       o A collaboration system template also using the boxed
         style but including post information such as username
         and date edited, and
       o A navigation system template wrapping the above menu item
         Please note that the navigation system is designed for a
         maximum of FIVE entries only.  You'll want to use a
         vertical nav system if you need more than this.


This is version 1.1 of the newfangled style:
Changes in version 1.1 include:
I've removed the sample pages and instead made it ready for the base webgui site instead as I think this will better reflect how people are going to use it and experiment with it.
I've also fixed up a few template issues that were causing it to not validate properly and added a login box and admin toggle.
