User:CKoerner (WMF)/Mobie web settings update

Some improvements to settings on the mobile website will be available this week:

User Features - Technical feature -
 * Font changer - This is an accessibility feature to increase font size of articles to read. a lot of mobile browsers do not have this feature in built. Accessibility is important to us, the feature has been in Beta mode for a while. we improved the way to change the font size and promoted it to stable [1]
 * Expand sections by default - for avid readers and editors, opening up sections every time on articles could be taxing. Now there is a setting that will open up sections by default [2]
 * Showing what changes are applied if a user enables Beta mode - Beta mode on mobile did not communicate to users what changes were getting applied to their experience. [3] This was a transparency issue as well as it helps us encouraging more people sign up for beta features by reading which features are available to test. This will help us collect feedback from more people about our experiments.
 * Use of modern UI library - Wikimedia Design has been developing style guide and UI library under OOUI framework. Mobilefrontend will use the components which are standard across other Wikimedia products. The components use accessible color palettes and UI states.
