Adding to the list of growing Gutenberg blocks, these two are worth a look:
- Secure Blocks for Gutenberg from Matt Watson is a block plugin that secures content by user role, allowing display of alternative content to logged-out users and users not assigned to roles.
- Easy Digital Downloads released the first version of their Gutenberg blocks a few days after WordCamp US. The blocks allow you to display a grid of your downloads on your site.
