Undo Redo
Undo Redo is a software design pattern that allows users to reverse (undo) and reapply (redo) actions in an application, typically in user interfaces like text editors, graphics software, or development environments. It involves maintaining a history of state changes, enabling users to correct mistakes or explore different options without losing work. This pattern is fundamental for enhancing user experience by providing control and flexibility over operations.
Developers should implement Undo Redo in applications where user actions are frequent and reversible, such as document editors, design tools, or configuration systems, to improve usability and reduce frustration from errors. It is particularly crucial in productivity software where users need to experiment or backtrack, as it supports non-linear workflows and boosts efficiency by allowing easy recovery from unintended changes.
