&gt; <i>It was a champion of the graphical user interface, where it is always possible to discover what actions are possible, clearly see how to select that action, receive unambiguous feedback as to the results of that action, and have the power to reverse that action—to undo it—if the result is not what was intended.</i><p>I think this is the best summation I&#x27;ve seen of the value of a well-designed GUI interface as opposed to the most common implementations of the command line. Obviously not everything can be plausibly translated to CLI, but I wish there was more effort to combine the power of CLIs with, especially, the discoverability and feedback of GUIs.
