==== User story
As a reader familiar with ZIM files or with a vested interest in using the Wikipedia offline, I want to be able to enable the feature in my Wikipedia app so I can do my online and offline reading in one place.
// Or conversely, 'As a reader uninterested in accessing large-files offline, I want to continue using the Wikipedia app without being distracted by the noise of seeing an unused like the Offline Library so prominently"
==== Proposed solution
Create a Setting in the app to give enable the Offline Library feature.
When enabled, the 'Offline Library' menu item becomes visible in the feed overflow.
| Initially no 'Offline library' in overflow {F10469089} | Settings with feature enabled {F10469082} | Overflow shown with Yellow50 colored dot to hint at the new menu item {F10469094} | Overflow opened with Offline Library menu item {F10469100}
Notes on design:
- Settings screen - update the header section from "Storage and syncing" to "Syncing and offline reading"
- Proposed new setting text:
- //Title =// Enable “Offline Library”
- //Caption =// Access Wikipedia article packs (shown as ‘ZIM’ files) that have been downloaded to the device for reading when you’re offline. __Find out more__ // <-- this links to an external web page with more info about the feature//
=== QA steps
#Open Wikipedia app where there is initially *no* reference to the Offline Library in the Explore feed or in the overflow menu.
# Go to the app's Settings and toggle on the "Offline Library" feature
# Give permissions for the app to view files in the device in the dialog that appears (if user says no, the toggle in step 1 will be turned off, since the Offline feature does not work if permission is denied)
# Return to the Explore feed where the overflow menu should now have the "Offline Library" menu option visible.
# Tap on the Offline Library menu item and check that a read-only version of the 'Offline Library' appears.
# Return to Settings and toggle off the "Offline Library" feature. Confirm that the menu option should once again be hidden.
