So I took a punt and installed Gutenberg here and set about reformatting the pages and recoding my layout plugin to use blocks. It all seems to work, but it’s a little sparsely documented and still has a few rough edges. There are a few things it’s weak on, especially around images and galleries, but that’s always been the case with WordPress.

Making this post has just highlighted that the tag cloud is missing.

Hopefully it’ll continue to evolve. Time to learn more JavaScript.
