Multiple product and set discount amount

Another possible bug.

I have a coupon set to discount $10 off a product. Add one to the cart apply the discount and all is well. Now if I change the number of that one item to 2 the discount amount should change to $20 which would be $10 off each item but it doesn't. It remains at $10.

When using total instead of percentage, the amount entered is taken off. It is not dependent on the number of products bought. If you want the discount to be affected by the number of products bought, you have to use percentages.
