I find that these give me a great overview of my project. I can get a sense of flow and completeness that I can’t get by looking at a small bit of the site as is usual for Rapidweaver and Elements. Not bad mind you, this just adds to it.
Ooh, I really like this idea as I often struggle to get a whole sense of a project when I’m only interacting with it one page at a time. Sure, I could recreate all of it in a graphics editor, but that create a lot of additional work that must be continually updated to ensure it accurately reflect the site in it’s current state.
I can see this being combined with something like a preflight check that would ensure all resources and links are valid and accessible.
