Anecdotally it (psychologically) helps some of my beginners students in Processing (young designers), because they feel less overwhelmed by their code when it has started to grow over their comfort threshold. As beginners their brain isn’t used to selectively focus and block out the rest, so folding functions helps them focus. It’s also a good way for me to end the moment when I show them how to extract some code out of the Processing main loop function into a separate function, “now that we invented our own command we don’t need to look at it all the time … and we could also put it in a library…”.
