Tax exclusive - 1 is not equal to 2 after update with regards to tax subtotal display
Tax inclusive - 3 is still equal to 4 after update

Ok this is great but I wish it could be turned off for people that dont need this. What I am going to miss the most is the sub total and the tax total ( sum of all taxes paid ). I will include a before and after picture so you can see the difference.

after

The inclusion of the tax amount column is great and is nice. But to remove the subtotal and the tax total does not make any sense.
