👉 The undo fluid, often referred to as the "undo" or "revert" mechanism in software applications, is a feature that allows users to reverse actions or restore previous states of an interface or application. It typically operates by maintaining a history of changes, enabling users to undo the most recent action or navigate back through a sequence of actions. This fluid design ensures a smooth and intuitive experience, minimizing disruptions and enhancing user control over the application's state.
