It would be great to have page templates for content editors. A bit like cms-collection pages in Webflow but without the cms. Content-editors would be able to add pages based on a predefined template (and content-blocks) and then change the content.
This way they would be able to create pages that follow the same basic structure (the same header and footer for example), but can be built out using content blocks.
The page template stays manageable in design mode though, so design changes there would apply to all pages based on it.
Content editors would have to get access to page settings to set the right page name, slug, search info etc.
