If you want specific tasks for designers, here are some:
- Expand and reorganize Preferences
- Add an actual page for history with dates and times, filter, grouping, etc.
- Add an actual page for bookmarks
- Add a profiles button to easily switch between them
All of these require intensive input from designers and are a net-positive improvement, as opposed to the 4th redesign of the exact same scope.
What OP explained isn't arbitration. When you don't pay off your bills, they go through a shortened court process in which you haven't got any representation.
The claimant merely submits their records of the claimee owing them. Then the case is either upheld and the claimee gets 10 days to fight the case or pay before their accounts get impounded, or the case gets thrown out.
The claimee doesn't have any say in the entire process - they can only raise issues after they get the stern letter to pay.
Since there's no representation for one side, it's not arbitration.
