Loving the advances made in the Gutenberg Project. Currently exploring Full Site Editing block themes with

Full-Site Editing is a brilliant evolution that puts so much power into the UI in an appropriate manner.
Some changes represent a scaling back of the UI, part of which means removing Customizer menus, presumably as the next step towards its final removal from core. Currently it seems the only way to access the customizer is by navigating to the active theme in the dashboard and clicking on the Customize button. Since I’m not fully ready to let go, I’ve added the submenu back to the Themes menu in pbrocks-fse as seen in the post thumbnail.
