MobileFrontend/Wikipedia navigation

Wikipedia Navigation UI is a UX design that will be deployed on multiple mobile platforms, including mobile web browsers, WAP browsers, iOS apps, Android apps, and others. There will be differences across platforms and the most comprehensive version will be for mobile web browsers, where all functions not included in basic browser functions must be accommodated in the UI that accompanies Wikipedia.

A related design is known as Athena, which is focused on making the main Wikipedia site mobile-friendly. This design is focused on optimizing the reading experience as well as accommodating contributory functions as they are developed, leading eventually to more complex editing functions. In a sense, Athena is a sort of "destination" for the evolution of this design.

Design goals
The main goals of this design are as follows:

(tablet versions can be developed later)
 * A rational, easy-to-understand framework for the placement of functions related to Wikipedia
 * Simple, obvious access to these functions in a way that conserves screen real estate
 * Flexibility to add more functions over time in different categories - i.e., extensible without becoming cluttered or non-intuitive
 * Compatibility with different mobile platforms and form factors - the minimum versions of this design should include:
 * web browser on iPhone
 * web browser on iPad
 * web browser on Android smartphone
 * web browser on Android tablet
 * WAP browser on typical Series 40 device
 * iPhone app
 * iPad app
 * Android phone app
 * Android tablet app

Functional categories
The main categories of functions that will be included in the UI are as follows:
 * Article-specific, such as inter-wiki language versions, related images
 * General to Wikipedia, such as notifications, featured content
 * Account-related, such as login, watchlists
 * Contributory, such as photo uploads, article feedback
 * Editing, such as photo patrolling, proofreading edits, visual editor, new page triage

Approximate roadmap
Here is a rough breakdown of what features could appear when in cumulative fashion:
