Very often, faced with complex presentations, looking at the objects (parents-children) present in A&O, I find it difficult to understand the functioning of the program, both for the quantity of such sequences and for the language in which these instructions are expressed. I suggest integrating the sequence of instructions being processed with a reverse slash (like in old DOS compilers) which displays in real time what the program is doing. Alternatively, the A&O instructions could be given a progressive numbering following the program progress.
I apologize for the translation but I hope I have clarified the concept.
Thank you.
