Contentful-Wizard is a JavaScript library that helps authors and content editors visualize entries and content types in their applications, making it easier to understand the visual relationship between elements and their corresponding content. The library creates links to the respective entries in the Contentful web app, allowing users to discover more about the content. It can be customized and supports easy integration with modern JS frameworks, usage via npm or as a standalone .js file, and provides a thorough explanation of its features in the README.md. The library is an example of how Contentful's extendable architecture can be used to implement custom components, and it offers a roadmap for future features.
