What I like to achieve is the next:
1- All unit prices in the cart must be tax-included prices.
For example; the tax amount in The Netherlands is 19%. I have a product which costs 100 euro without the taxes. The unit price should be 100+19=119 incl. taxes as default unit price.
2- Total tax amount in the cart
A customer orders 10 of this product. So the cart totaal should be 119x10=1190
I also like to have the sub-totaal 1190.
But stil the total tax amount in the picture = 119.
