I'd love the ability to build a site-wide template page that can be used to build all of my pages on site-wide (just like the current CMS templates - but for non CMS pages or entite site - basically wherever you choose to use it). This would be so helpful for adding site-wide elements to sites that have already been built. For example, my clients site is already built, but client has asked to add a static feedback tab to all pages. I now have to go through every page and add it manually. A site-wide template would save so much time!
