It's not magic, or sleight of hand -- it's a new Scripting2 feature. Posts that are not part of the chronology.
Over the years I've made various tools that create web documents in the OPML Editor. They never turn out to be as powerful as the blogging tools I develop, because that's where I focus my efforts. So I figured to get the best web document editing tool, I should just be able to use the blogging tool to make "standalone" documents. For change notes pages, and howtos, etc.
If you see this but not the post about development, then it worked. ">
