Hi Ulysses, nodysseus looks great! It's very similar to what we (I wasn't working alone most of the time) wanted to implement: Having a tree of your code where you can see every intermediate value, being able to change the program and immediately see the result etc. On the other hand, I suspect many here are trying something like that, it's basically the blueprint given by SmallTalk or Bret Victor or so many other people. 😅 I always thought this type of interface doesn't suit the mouse-keyboard interface very well, but seems to much better fit a touchscreen. What are your plans/thoughts?
