Thanks @Nikolay for these informations.
I wish I could gradually remove the smoke, but I don’t know how to do it in a simple way.
I would also like to make a much simpler questionnaire for my K8 or even K7 students.
I would need to be able to hide (collapse ?) most of the functions, showing only one or two functions and the main loop (perhaps without a loop). See more details in this post.
Is it possible ?
Thanks for your help.
