Here is a great example of Gutenberg’s granular control over the content. Wholesome Publishing expands on Gutenberg’s core functionality, similarly to what Editor’s Kit does, by providing visibility control over each individual block by letting us set individual blocks as drafts, and introducing block based comment threads.
The first feature does not require too much explanation. We can set an individual block as “draft” to prevent it from being publicly visible:
Once we change this, the “draft” block will be dimmed a bit, which is a nice UI detail. You can see an example of how this will look in the editor, the middle paragraph has been set to a draft:
If we open the code view, this is what the markup for the drafted block looks like:
<!-- wp:paragraph {"className":"eplus-AP3RnP","isBlockDraft":true,"uid":"1596646820543","epGeneratedClass":"eplus-AP3RnP"} -->
<p class="eplus-AP3RnP">Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. </p>
<!-- /wp:paragraph -->The second feature this plugin brings in is the ability to insert per block comments. I love this particular feature because this is something I specifically anticipated in my 2018 WordCamp Bilbao talk, a while back and 7 months before Gutenberg was released into WordPress core.
Comments can be added in the editor itself, and are listed under a custom sidebar, as seen below. I understand having them showing in the frontend in a visually correct way (i.e., next to each block) would require custom theme support.
You can read a detailed review of this plugin over at WPTavern. The plugin was also mentioned on episode 23 the Gutenberg Changelog Podcast, which is where I heard about if the first time.
