Quartz Composer had a very similar sort of level of ease of use. Drag some components out, wire them together, add some AppleScript or JavaScript if you want. And of course Apple has let that whither on the vine for the last ten years. I still use it on occasion to debug HID devices because it’s so fricken easy. Drag out the HID block, pick my device, drag the value I want to inspect onto a text render block. Done. Updates in real-time, essentially built an HID oscilloscope. Update - old video of me using it to inspect a keyboard - https://twitter.com/donatj/status/1223093796558209026 https://twitter.com/donatj/status/1223093796558209026
