When you have a large number of reports in your work queue, finding a completed or still-active report can mean a lot of scrolling. We've addressed this by adding a time period filter alongside the existing status filter (completed, to-do, etc.). You can now filter by period - for example, the last 5 days or the last week.
The filter option is shown at the top of the reports overview - see the screenshot below:
To make things even easier, the app remembers which option you last selected and restores it in your next session, so your overview always shows exactly what you need.
