Reading/Web/Desktop Improvements/ja

It has been 10 years since the current default Wikimedia skin (Vector) was deployed. Over the last decade, the interface has been enriched with extensions, gadgets and user scripts. Most of these were not coordinated visually or cross-wiki. At the same time, web design has evolved. It is time to provide the best refinements as a part of default experience of all users, on all wikis, in an organized, consistent way.

Our goals are to increase the utility amongst readers and maintain utility for existing editors. We will measure the increase of trust and positive sentiment towards our sites, and the utility of our sites (the usage of common actions such as search and language switching).

Initially, on most wikis, only logged-in users will be able to opt-in individually. On selected wikis, our changes will be deployed for all by default, and logged-in users will be able to opt-out. We are hoping to increase the set of early adopter wikis gradually, until our improvements are default on all wikis in 2021.

Currently, the interface…
'''…doesn't match the expectations. …is cluttered and not intuitive. …doesn't highlight the community side. …isn't consistent with the mobile version.'''


 * 1) The desktop interface does not match the expectations created by the modern web platforms. It feels disorienting and disconnected. Navigation and interface links are organized haphazardly.
 * 2) There is clutter that distracts users from focusing on what they came for. It is challenging for readers to focus on the content. It is not possible for them to intuitively switch languages, search for content, or adjust reading settings. New editors are unable to use their intuition to set up their account, open the editor, or learn how to use non-article pages for moderation purposes.
 * 3) A very small percentage of readers understand how Wikimedia wikis function. Many readers are not aware that the content they are reading is written by volunteers and updated frequently, or that they can potentially contribute as well.
 * 4) The large difference in experiences among our desktop interface, apps, and the mobile web, makes it difficult for readers to connect our products. There is a lack of unity in the concept of Wikimedia sites.

Principles
'''We will not touch the content. We will not remove any functionality. We are inspired by the existing gadgets. We will not make major changes in single steps. We will not touch other skins than Vector.'''


 * 1) We are working on the interface only. No work will be done in terms of styling templates, the structure of page contents, map support, or cross-wiki templates.
 * 2) Elements of the interface might move around, but all navigational items and other functionality currently available by default will remain.
 * 3) We have analysed many wikis and have noticed many useful gadgets. Some of them definitely deserve to be surfaced and be a part of default experience.
 * 4) Though our changes will be easily noticeable, we are taking an evolutionary approach and want the site to continue feeling familiar to readers and editors. Each feature will be discussed, developed, and deployed separately.
 * 5) Skins other than Vector are out of the scope of our adjustments. We will freeze the current Vector to Legacy Vector, and will deploy our features as parts of the new default Vector.

Deployment plan and timeline
Test our features individually, share feedback, and join our early adopter wikis!


 * 1) It is our intention to test our improvements in collaboration with a diverse set of volunteering early adopter wikis, both Wikipedias and sister projects.
 * 2) Both prior to development and after deployment, we will be collecting data (via A/B testing, prototype feedback rounds, etc.). In the case of significantly negative results, we will roll back our changes.
 * 3) First three features (the new header, collapsible sidebar, and limited content width) will be deployed in June/July 2020. Our hope is to develop a few more features until the end of 2020.
 * 4) We are hoping to increase the set of early adopter wikis gradually, until our improvements are default on all wikis in 2021.

What features will be added
We have not created a complete, detailed product specification. Each feature will be built and implemented separately, over time. Features which have been created are still being adjusted and improved. Our decisions are based on community feedback, user testing, and extracted API data.
