Thanks Jonathan, that is just excellent again. I, these days, dedicated myself to get myself out of my chair (I program standing up for around 7 years now but that's not enough getting older); my goal is being able to walk while programming. And so many interfaces you have here can never even aspire to do that. I finally am at a point with something (after 10 years of having this same goal behind me and about 40 failed attempts with prototypes) that I can say it is not slower than sitting down while walking (I am well aware this is also related to getting older; I am capable of doing far more in my head than I was 20 years ago). And it is interesting to see how all these interfaces depend on your being stationary and some not even only stationary but stationary in front of a quite massive screen (visual programming often needs rather large surfaces for anything trivial).
