Atlas lets you change all front-end labels from within the admin interface. You get sidebar options for categories, search results, home, and articles to give you more flexibility on what to display on your pages. Webmasters have the option to enable Gutenberg / Font Awesome and modify permalinks and CSS in the back-end.
