I quite agree with your two points above.
"Section for practical code examples." They could be added to the method descriptions, and not just sample code strictly related to a given method, but code showcasing typical scenarios with related methods and often used techniques, "coding patterns".
"Currently a lot of core features are very fragmented and hard to find if you don't know they exist in the first place." So true! I have some notes of some important settings, which I often set up differently from the defaults, but having to look through them just to find something is time consuming. Some sort of clever way of gathering information and providing it in a categorized and digested way would help, I think.
