provide a "compare to" option of same day of the week last year
You currently offer a sales comparison with the same date of the previous year, but not the same day of the week. Our business is heavily variable based on the day of the week; comparing Saturday, June 5, 2021 to Friday, June 5, 2020 is not very useful. But comparing Saturday, June 5, 2021 to Saturday, Jun 6, 2020 would be very useful. Our previous point-of-sale system offered this functionality.

The Manage My Business app in the Clover marketplace offers this feature, both for monthly and yearly comparisons. It also supports yearly comparisons for holidays like Easter or Mother's Day, even though the date changes from year to year.
