Any chance GP has a layout block that essentially wraps the unsemantic library so we can just add a 1-3 (or more?) column block and visually edit content?
for Columns we would suggest using the Columns Block in core.
We have developed a GP Section Block like Sections for Gutenberg. But during our development we discovered a bug within Gutenberg that requires fixing before we can release it. Whilst the bug exists any 3rd Container Blocks can cause content lock-in or lost content which isn’t good. Hope they update with the fix soon.
