How should "Home" pages be represented in an app's navigation structure?
Some apps have an explicit "Home" page that's always visible when the app is launched normally. For example System Settings and Discover.
However we aren't consistent about how we represent this page in the app's navigation.
System Settings omits it from the sidebar, and you access it from a button on the toolbar. Discover does the opposite.
I don't have a massive preference for one or the other, but the differences between them represent an inconsistency we should strive to eliminate. Maybe there's a slight advantage to having it in the sidebar rather than the toolbar since it re-uses an existing navigation structure people use to navigate the rest of the app. But then, what about simpler apps without navigational sidebars?
After we decide something, I'll write the conclusion in the HIG.
