#### Background
The Android and iOS mobile apps have had the saved tab and custom reading lists for many years now. They have had slightly different functions on Android versus iOS, but custom lists have always been shared and synced on the server. This year, the Web team is adding a "Saved" function, and they will support saving articles to one list, and soon after custom lists. We want to make sure that the experience matches across Web and the mobile apps when users simply saves something, and adds it to a custom list.
#### User story
As a Wikipedia reader who uses the Saved tab, I want an "All Articles" view that shows everything I've saved across all my collections in one place, so that I never have to browse individual collections to find a specific article.
#### Requirements
**"All Aarticles" view**
- Add an "All Articles" option within Saved; it should appear in the list of collections- Add "All articles" option within Saved,
- "All Aarticles" displays every article saved across all collectionslists, including in the default list, and custom lists
- Articles appear only once, includingeven if the default list and custom collectionsy belong to multiple lists
- Articles appear only once, even if they belong to multiple colle- Custom lists remain unchanged and continue to functions as before
- Custom collections remain unchanged and continue to function as before - When viewing "All articles", each article should show which custom lists it's on within Saved (match current behavior when searching for an article within teh "Filter" funtionality)
Update filter to search
- When viewing "All Articles", each article should show which collections it belongs to (match current behavior in the Filter functionality)Change "Filter" functionality to a Search icon
- Do not allow users to rename, - Search whichever view is active: if All articles are active, search article titles. deleteIf Collections view (reading lists) is active, or reorder the "All Articles" listsearch through reading list titles (matching iOS functionality)
**Search**Unsave behavior from Saved tab
- Change "Filter" functionality to a Search iconUnsaving from "All Articles" removes the article from ALL lists it belongs to: it is fully removed from the user's saved content: Show a confirmation prompt before deletion (See iOS for precedent), Prompt must clearly communicate that the article will be removed from all lists, not just one
