The new green discount that shows on coupon prices should be optional. One thing is, that the feature is crazy buggy and should never have been released and the numbers shown only on rare occasions make sense (status on April 15th), the other is, that the feature might make sense for global coupons that are specific discounts, but since coupon prices on products are not actually discounts but specific prices it only makes sense in a (small) number of cases. In a lot of coupon code price cases it's not actually a discount, it's a price with a bonus, it's a way of tracking (different codes for different landingpages or ads), and it's very common to have more than one price with the same code, which the function currently can't handle at all.
So please give this feature a toggle (and set it to off for existing prices, so we don't have to go through hundreds of coupon prices to turn it off) or restrict it to be for global coupons only, where it makes total sense.
Same goes if the plan is to extend this feature to include secret prices as well.
