This project involved creating a Google Chrome extension that utilizes Twilio for making calls and sending SMS from the browser. The extension consists of a manifest, popup, and background script, which communicate with each other to achieve this functionality. The development process was straightforward, and the use of WebKit debugger tools made it easier to identify issues. The project also utilized HTML 5 features such as localStorage for storing information in the browser. Additionally, AppEngine was used to host TwiML, enabling the extension's core functionality.
