The Salesforce Schema Builder Expander is a Chrome add-on developed by concret.io. This free tool is designed to enhance the functionality of the Salesforce schema builder by providing users with more screen real estate for visualizing their schemas.

To take full advantage of the expanded viewing area, users are instructed to enter full-screen mode and hide the sidebar. Additionally, this extension hides the top header section, providing an extra 1-2 inches of screen space.

It's important to note that the Salesforce Schema Builder Expander only activates when users are on the Salesforce schema builder page, ensuring that it doesn't consume unnecessary machine resources when not in use.

With the Salesforce Schema Builder Expander, users can easily view and navigate their Salesforce schemas with greater ease and efficiency.
