===Why are we doing this?
Based on user testing, the hints that appear after a user saves an article are too short. Additionally one user thought that she had to tap on the hint to save the article. Finally there are some small bugs currently with the hint behavior that we should fix.
===Proposed solution
- Increase the length of time that a hint is shown by 5 seconds, unless a user begins scrolling
- If a user scrolls after saving the total hint visibility time should be reduced by 5 seconds (eg. stay the same as now), scrolling should //not// cause the hint to stay active indefinitely.
- Update the hint text to 'Move [article title] to a reading list?'
- If a user taps on the hint and selects a reading list, the article should be removed from the default (Bookmarks) list and instead added to the chosen list
