ver_1.2.037 is bringing a couple of long awaited features:
Feature: it’s now possible to control item quantities and remove items directly from the order summary area of the checkout page.
Feature: billing and shipping address address lines are equal and can both be exploded to separate rows.
Lots of other fixes to improve the extension are also in place including better integration with Braintree/ PayPal. Find more details about those in our changelogs.
