1 - show the parameters at the bottom of the report so you don't have to push "Change" all the time
2 - For the second report, where there the LHS and RHS are the same reports, we need the following options:
Past Day-> Previous day, Same day last week, Same day last month, Same date last year

Past week -> Previous week, 4 weeks ago, Same week last year

Past month - > Previous month, Same month last year

Past 6 months - > Previous 6 months, Same 6 months last year

Past Year ->Previous year

Custom -> Previous year (shift all dates 1 year earlier)


3 - When left and right are different, add checkbox for "same time period"
4 - Make a "Run both reports" button next to the view dashboard.
