It may become better designed or maybe not. I did not read the code in detail because of too little time to decifer the code.
Maybe I was a bit unclear on this: if there is indeed not a single logical boundary in the function, then well, tough luck. Then this is one of the rare cases where there's just no good solution. Even with an increased character limit, the function would not be that much more readable. It would still be too long to get a good grasp of the structure quickly.
I did not mean that arbitrarily cutting up the function would be a solution, just that usually it is very much possible to decompose and achieve increased readability. That's why I used the word "indication" in my last sentence.
