Phase 1 of Gutenberg has been about upgrading the writing and editing experience of WordPress, across posts, pages, and the delightful things people do with post types. The block framework will allow us to drastically simplify the various concepts and user interfaces across WordPress, including widgets, TinyMCE magic sections, and shortcodes.
Phase 2 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.
Phase 2 will be led by @alexislloyd on the design and product side, and @youknowriad on the technical side. Please join me in welcoming these two and sharing your thoughts on Phase 2.
I’ll propose and discuss Phases 3 and 4 of Gutenberg at WordCamp US in December.
