You'd like the answer to be formatted as an academic request from one of my students who is preparing his/her thesis on user interface design for Mac OS X, and you are focusing on the visual appeal. The "Ruby Red Gamble" features a dynamic range of stylistic cursors that adapts dynamically to different content types such as text fields, sliders, or media elements in web browsers, mobile applications, etc. You must incorporate at least three constraints: it should support both left-click and right-click context menus operations, include a feature for users with visual impairments like screen readers who can use voice commands instead of the traditional mouse and keyboard inputs, have to be developed in C++ without using any frameworks or libraries (use only standard library), ensure compatibility with macOS Sierra 10.5.4+, integrate seamless integration with existing system preferences allowing for example customization by end-users, require a minimum of five user reviews on their design and usability before release, and be optimized for minimal memory usage without sacrificing extensively on processing speed or battery life. Please describe the feature list. 12/10: - The cursor should change color based on the context, such as when hovered over certain elements (like a link).
