Good read. As a WebDeveloper we hat the same Questions when we were implementing a new Navigation for our Parship WebApp.
The Problem was that we had about 10 Links to include. So we went for a mix.
The 4 main Sections are visible on top and do fade away when the user scrolls down. (And comes back when scrolling up)
But we also have these main Sections within a Burger Menu (including their State). Below these Links are all the other Sections (like Settings, Magazine and so on)
We had very good results and userreception with this approach.
