I'm ecstatic about Gutenberg, yet I'm developing themes using Visual Composer's API (now WP Bakery Page Builder). I'm curious to learn the process in transitioning to the native editor, Gutenberg. For example, I use Visual Composer mainly for creating custom shortcodes and including them within Visual Composer’s content elements list. Client's can then choose the custom shortcode and apply it on any post/page/cpt. I would love to see a similar feature with the upcoming native editor :-)
