ability to remove tax from a product based on the customer entering a VAT ID i.e. display "I'm a business" + a "Please enter your VAT number: [ ]" field -- if entered, then no tax would be applied/charged. that way, we don't have to setup separate product variants for B2B vs B2C + ensure that tax calculations are correct on the back side when exporting orders to total taxes additionally, it'd be great to have the ability to show tax on product page with tax or without tax (i.e. if you include tax in your prices)
