In regards to the length of functions, to me it comes down to whether it is preferable to have the entire content of the function visible to the programmer at the time any changes need to be made, or if there are multiple things going on that can be assessed independently of each other. The idea of setting a hard rule that a function can only be as long as your screen height ignores the context is what is being done within the function, and encourages the programmer to make breaks in places where it may not make sense to do so.
