In reply to Nick.

And because the plugin uses CPT and Gutenberg, and no Custom Fields, you can very easily export your Patterns from the Tools->Export screen, and install them in any other website.

I did not even think of that possibility. Good point.

At this point I’m guessing that in the future the Patterns would be allowed to be organized in Categories...

I would assume we would get categories and/or collections for patterns in the same way that blocks work. When that happens, I plan to create a taxonomy to allow users to group their patterns with the plugin.

...it would have been nice to have a feature to export the php code needed to register the patterns in our products...

That was on my mind too. I am not sure how to handle that just yet, but I would be happy to see anyone submit a patch that makes it happen. It would be really useful to have a direct copy/paste method with the PHP code included.
