With the Bulk Variation plugin, there is something that isn't really user friendly for the customer.
For instance with T-shirts, if someone is ordering a bulk order, they more than likely will be choosing the same color shirt but in different sizes.
Problem is when you click the "add variation" button they color option will default back to the default color. What would be better if after clicking the "add variation" button it would keep the same color selected.
Better yet, it would keep the same color selected, but bump up the size selection to the next attribute in order.
This seems like it would be a great improvement on customer usability.
