I think it would be useful to add a new checkbox to the 'Navigate' section of the View tab, called 'Display Matching Page'
When checked, Design would automatically swap to the first Design Page that has a true condition as you move through the data pages.
If you are working with data that has multiple document types in it, the advantage is that you don't need to go back to the Document Structure tree to find the correct page layout for the type of page you're viewing. This can be difficult if the tree is also expanded.
