More flexibility on the period selection. With the current options, we keep running into the issue that we can't look back at certain moments. A concrete example: we wanted to view the percentages from two weeks ago, but that isn't possible within the selection that's currently available.
What would help here:
Filter by month (January, February, March, etc.)
Filter by week (week 1, week 2, week 3, etc.)
That way you can look back at a specific period more precisely, rather than being dependent on the fixed time frames we have now.
