Gutenberg phase 1 has just come to a conclusion with the release of WordPress 5.0 which has been about upgrading the writing and editing experience of WordPress, across posts, pages, and the delightful things people do with post types.
The next phase seeks to expand this idea beyond the post, allowing editing and customizing the rest of a website in WordPress. This process also aims to eliminate the complex obstacles users have to find their way through — like multiple layers of abstraction and navigation — and to reduce the amount of technical knowledge required to customize the overall appearance and functionality of their site.
Now WordPress is about to start the Gutenberg Phase 2! Which is about thinking outside the box, namely the post and page box, to allow Gutenberg to handle entire-site layouts. We will replace widgets with blocks, so any block will be able to be used in any registered “sidebar” for legacy themes, and we will upgrade “menus” to a navigation block. It will take the ease of use that was introduced with block-based editing and extend that capability to the Customizer, starting with widgets, to make it easier for users to customize the rest of their sites.
The first step of the Phase 2 will bring blocks into the Customizer to create an ease experience for the common users and the developers creating a path of upgrading themes to Gutenberg.
The next long step will begin then; it will expand the current Gutenberg post and page editor to become a full-fledged site editor, bringing everything together into a unified and modern product experience.
Phase 2 will be led by Alexis Lloyd [@alexislloyd, http://www.alexislloyd.com/ ] on the design and product side, and Riad Benguella [ @youknowriad , https://twitter.com/riadbenguella ] on the technical side.
