I'd love to try to prototype a GUI that harmonizes GUIs with keyboard accessibility; bring back some external component model to script them again, put some sort of effort into making that scriptability discoverable for users and easier to maintain for developers than Applescript was, make it easy to give and surface expert-level shortcuts, make it so keystrokes are buffered across contexts so you can develop expert-level skills in pre-keying what you want the UI to do even before it pops up (one of the reasons why you had to pry the console-based point-of-sale software out of customer's services hands at gunpoint), and just generally make something useful for experts again... but it's years of effort to even prototype such a thing to the point where it's useful for anything. GUIs are stuck in the 20th century because they're just so big.
