Gmail Contacts Card Updater is a free Chrome extension developed by gmachine. It falls under the category of Browsers, specifically Add-ons & Tools. This extension enhances the little card that appears when you hover over someone's name in Gmail by adding relevant information from your Google Contacts account. It includes email addresses, phone numbers, and addresses, providing you with a quick and convenient way to access important contact details.

The extension is simple yet incredibly useful, especially for users of Google Voice. It allows you to have all the necessary contact information right at your fingertips while using Gmail, eliminating the need to switch between different applications or tabs. The added convenience and efficiency make this extension a valuable tool for anyone who frequently communicates through Gmail.

While the extension generally performs well, there are a few remaining bugs that need to be addressed. Occasionally, the extra contact information fails to load, which can be frustrating when you rely on it for quick access to important details. Additionally, the extension's appearance is not optimized when the contact has an employer. These issues should be resolved to ensure a seamless user experience.

If you encounter any further bugs or have suggestions for improvement, the developer, gmachine, welcomes feedback. However, it is important to note that personal or contact information should not be shared in any communication with the developer.
