"I think multiple levels of undo would be wonderful, too"

This quote by Bill Joy recommends that he thinks that having multiple levels of reverse would be helpful. By having several levels of undo, it would permit users to go back several actions in their work, instead of simply one. This could be specifically useful for tasks that require a lot of steps, such as coding or designing. It would also be advantageous for jobs that need a lot of accuracy, such as modifying pictures or videos. Having multiple levels of undo would allow users to go back and repair mistakes without needing to begin with the beginning. It would also enable users to explore different concepts without needing to stress over making errors. In General, Bill Joy's quote suggests that having numerous levels of undo would be a terrific addition to any task.
