Features that aid consumption, either by improving the presentation of e.g. a Wikipedia article for the purpose of readability, or by surfacing supporting content (images, videos, spoken versions) with better affordances and improved flow.
2. Search
Features that improve integration of search into the site and intuitiveness of all search features, relevance of search results to a given query, search across different content sources, search performance, multilingual indexing, etc.
3. Customization/Discovery
Features that suggest useful content based on user behavior, or that surface related and relevant content (related articles, sister project content, etc.), or that hide content that's not desired (e.g. graphic depictions of violence)
4. Export
Features, technologies and applications that make Wikipedia content available in formats suitable for re-use, either in ways directly relevant to the reader (e.g. PDF or OpenDocument download) or in indirect ways that can be built upon by others (e.g. downloadable XML files).
5. Navigation
Features which improve basic site navigation, increasing the discoverability and usability of highly desirable site features (e.g. improvements to category access and navigation, surfacing frequently used navigation links more visibly, improving navigation labels to be more obvious).
6. Mobile/tablet device experience
Features and technologies which leverage device-specific capabilities (e.g. geo-location of relevant articles via GPS, touch navigation, augmented reality), and which format content in device-appropriate ways (e.g. smaller screens), to improve the reader experience, especially with regard to the large categories of smartphone and tablet usage. This category of functionality needs to be understood in close connection with participatory functionality targeting this category of devices.
Features which highlight ways for the reader to improve a Wikimedia project, ideally relevant to their actual usage and likely ability to help. This may be achieved by first promoting affiliation ("Join WikiProject Medicine!") before inviting participation.
2. Entry vectors
Features that allow lightweight participation and which are designed to transition users to deeper engagement. This may include persuading readers to join an off-wiki event like a meetup, workshop or conference.
Features and technologies that relate to surfacing friendly and easy-to-understand information in key locations. This may include interactive tutorials, tours, etc., but generally is likely to only be lightly technology-dependent, with the exception of analytics to compare the effectiveness of different approaches.
2. Mentoring tools
Features that relate to connecting new users with experienced mentors who can respond synchronously or asynchronously to a new user's questions, expressed intentions and actions, and features which help manage and evaluate mentors/mentee relationships.
3. Advanced user interaction
Features that systematically ease friction between new and experienced users.
Technology to deprecate wiki syntax as the primary input method used to create content in Wikimedia projects, and to instead make it possible to compose complex pages using a rich-text-editor which also intuitively represents templates, magic-words and other wiki-specific paradigms.
2. Block-level text editing
Technology to make it possible to make quick in-place modifications to individual sub-components or sections of a page, e.g. sentences, paragraphs, sections, templates, categories, captions, citations.
3. Improved code editor
Technology to deal with wiki markup and other code more effectively (e.g. syntax highlighting, code folding, improved preview workflow).
4. Real-time editing
Technology that enables multiple editors to work on the same document synchronously, and to track changes irrespective of creating an explicit revision (e.g. near-atomic change history that can be explored through a time-slider).
5. Multimedia
Technology that makes it easier to upload, create and manipulate images, sounds, music, animation, video, or any combination of those media (combinations may also include text and some form of interactivity).
6. Data
Features that relate to making structured and tabular data easier to enter and revise, e.g. forms, spreadsheets.
7. Template code
Features that relate to replacing or enhancing the current template programming system.
8. Specialized content
Features that relate to editing domain-specific or otherwise specialized content, e.g. music, mathematics, graphs, timelines, symbols, but also project-specific content such dictionaries (Wiktionary) or digitized text (Wikisource).
9. Large-scale editing
Features that make it possible to efficiently make additions or apply changes across a large number of pages.
10. Maps/geodata
Features that relate to embedding and editing maps or geographic metadata associated with content.
11. Device-specific contribution
Features that allow the contribution of content by leveraging capabilities specific to the device that the user is using.
Features that enable more effective collaboration in (typically subject-matter oriented) groups of individuals. This is closely related to B.1. (opportunity discovery) where such features make it easier for readers/new users to join WikiProjects.
2. Process/workflow support
Features which support creation of and participation in processes with a pre-determined flow (e.g. Featured article candidates, Featured picture candidates, Requests for adminship, etc.)
3. Discussion and chat
Features that improve people's ability to communicate in relation to their Wikimedia activity.
4. Broadcasting tools
Features that allow individual users or user groups to broadcast messages to some class of recipients.
Features which support the process of localizing MediaWiki's user interface into all supported languages, and which enable locale-specific user interface message transformations.
2. Text input and rendering
Features which enable text input and rendering using a language's character set.
3. Collation
Features that order sequences of words or phrases correctly according to a given locale.
4. Search indexing
Features that increase the likelihood that searches return expected results in a given language, both using internal search and external search engines.
5. Multilingual wikis
Features that support content in multiple languages inside a single wiki.
6. Multilingual discussion
Features that support overcoming language barriers within the context of a single discussion.
7. Translation and cross-language collaboration
Features that support translating content from one wiki to another, and otherwise working together across languages on versions of a page
8. Translation memories/glossaries
Features and technologies that support re-using translations and standardizing terminologies.
Features and technologies which enable users to share identified activities such as article creation, file uploads, etc. on social media feeds.
2. Find friends from social media
Features and technologies which make it possible to transport your social graph to Wikimedia wikis. This assumes the existence of a local social graph, although it could be a rudimentary one.
3. Authentication and authorization
Features and technologies which allow a user to identify themselves (and any additional credentials and reputation), and that assign rights to a user based on their identification, either within a Wikimedia project or within an ancillary Wikimedia service.
4. Discover/review/import free content
Features that leverage the APIs and feeds of other websites for the purpose of updating or importing content.
5. Cross-wiki integration
Features that create a more consistent and persistent experience across Wikimedia projects.
6. APIs
Features that expose Wikimedia functionality through machine-accessible interfaces.
