The Advanced Rich Text Tools for Gutenberg is a free WordPress plugin designed to enhance document management capabilities within the Gutenberg editor. It introduces essential formatting buttons, including code, subscript, and superscript, directly into the formatting toolbar, making it easier for users to apply specialized text styles. Additionally, the plugin features an inline text and background color panel, allowing for greater customization of content appearance, currently accessible from the block sidebar.

Another key feature is the remove formatting button, also located in the block sidebar, which provides users with a quick way to clear unwanted styles from selected text. This plugin is particularly valuable for business and productivity needs, streamlining the content creation process and ensuring that users can effectively manage their documents with enhanced formatting options.
