> most GUI toolkits like C# Winforms, C++ Qt, HTML buttons, etc do not include a macro recorder in the default event loop. Therefore, to "reify" the GUI in the same fashion as chess programs or the audio software requires grafting data structures and programming extra code to "record" the button presses into a timeline. Programmers won't do this unless there's a customer need for it. (E.g. Photoshop lets you reify the GUI as "actions" for later playback")

In the MacOS System 7 days when Apple was still pushing AppleEvents/AppleScript heavily, a good portion of Mac software would let you record your actions in them through the AppleScript Script Editor (they would emit the AppleEvent equivalents of your GUI actions), generating an AppleScript which you could then edit. It was a fantastic system. It's still there in macOS X, but it's rarely supported/used now.
