I am happy to see your article that you give a very detailed explanation regarding the relevant topic. I agree with your all points and especially the point that hits me is your saying about tutorial and documentation that there is no more need to give a tutorial on it.

There are already very well explain features and I have also said in my article that the name of each option telling a common user that what can be the purpose of this option and for what purpose it can be used so its perfect tool in my point of view.
