Now any view can have a name in the URL - so that a module showing that App can easily change between views just by adding "Details" or "CategoryList" to the URL. Simple and powerful.
At the moment I can't explain much more - just try the settings.
Important to understand: 2-Keys
Since DNN rewrites the URL and always maps 2 values with xxx/yyy to xxx=yyy in the background, the key to activating a separate view must contain 2 values like Details/House or Categories/List
Because often the Details-View itself expects a further parameter (like a Details ID) you can also write Details/.* - this means that if the URL contains Details and another parameter of any value, it will also enable the Details view.
