In reply to Fat Brad.

I'd settle for "as difficult as making an Elementor Extension".

I don't know how many people have tried making an extension for Elementor, but it's really really easy. The documentation is sparse, but clear. And that's enough documentation because it's so simple. To add to that - all the pro-top articles only require 1 short page, because the foundation is so simple that even the protips are readable in one chunk.

If (native) Gutenberg block creation was as simple as making an Elementor widget that would be a massive improvement.

To be clear I'm talking about process here, nothing beyond that.
