This is a demo I've been using for a little while in my presentations. It's mostly meant to inspire and inform people on how far they could potentially go in using document extensions to manipulate the UI of their apps. The idea is that the app starts out very ugly until you apply the "brandingDemo" document extension to it. Once this extension is applied, the entire layout and look and feel of the app changes, and some tools are even added to it.
Again, this is not meant to be a solution someone could plug and play into their apps, however, the code could postentially be useful to someone looking to do the same thing.
