Gutenberg 7.2 Adds Long-Awaited Multi-Button Block and Gallery Image Size Option

The lack of an option to set the size of gallery images has been one of Gutenberg’s largest failures since its inception.
After years of this basic option for the gallery shortcode with the classic editor, the gallery block has always felt incomplete.
Gutenberg 7.2 introduces a “Site Editor” screen, which can be enabled by ticking the “Enable Full Site Editing” checkbox on the Gutenberg > Experiments admin page.
