Great but needs some more work

This is a great plugin. However, it needs some tweaking and fine tuning.
Firstly, the option to add a discount for all the products in an order in one shot doesn’t work. Second, when adding a discount to individual lines in and order sometimes it doesn’t work and you need to retry.
I would like to see the total before the discount then a line for the total discount then another line with the total payable.
as it is now you don’t get the total, that you have to add manually, it only gives you the total discount.
Again I would like o thank you for this plugin.
