Hi ACF! First of all thank you SO MUCH for all the hard work!
Our ACF implementation leans heavily on Flexible Layouts and using clones of field groups for things like Background settings (image, repeat, size, etc.). Before Gutenberg I was totally happy just using tabs to separate the Content fields for the flexible layout from the Background fields, but I feel like it’s not a great UX in the Gutenberg editor. It’s even worse when I switch to preview mode and all my tabs get crammed into that little sidebar.
It would be awesome if I could instead register my block with the content fields, but also somehow indicate another field group to use for the InspectorControls. Poking around in the source I didn’t spot an obvious way to do that. Are there any plans for this in the future?
