This is awesome. As a middle tier developer, I've come from the custom field and template realm of WordPress. I've been creating my own forms of blocks using custom fields. I like the idea of Gutenberg because it speeds up that process but I'm not adept at React so I've shied away from developing my own blocks.

I REALLY like that I won't have to download a plugin with a bunch of needless functions. It's my biggest pet peeve of themes and plugins. I'd rather have 30 plugins that each do something specific and needed then 5 plugins with 50 different features I don't use or need that add unnecessary files to my websites.
