Coordinates is a Chrome extension for adding a mouse position tooltip, with its x and y coordinates. It also measures areas of regions, such as a certain region on the page or certain elements on the page. It measures the areas of text, images, and links, as well as rectangles, circles, and lines.

It is designed to display its values on any element on the page, including buttons, labels, text boxes, text links, and images. It is designed to work on almost any page and is easy to use.

For more advanced usage, it offers various options such as a button with a tool-tip that can display a text on a background page and update coordinates on its parent page.
