Mobile design/Navigation improvements

This document describes plans for improved site navigation on Wikimedia mobile sites.

Rationale
As we add more features, especially contributory ones, to the Wikimedia mobile gateway, we need to adjust our site navigation to make them more discoverable. We also need to ensure that our site architecture follows usability best practices.

User research
Previous work on mobile site navigation has shown that the left navigation menu (the "hamburger") is discoverable and is an understandable affordance for users. Users also strongly gravitate to the search bar in tests, indicating that this is an important feature to have available on content pages.
