price order by

Hello, is it possible to add options in the ‘search by price’ option to order the results? (I configured it as dropdown).
I don’t want to have 2 buttons for the price:
– your filter price button (that it likes me a lot)
– the standard woocommerce button

2 more questions:
1.- The empty attributes are not hiding when they are 0 although I have the ‘Hide empty terms’ to yes. Can you confirm me that in the paid version it works?
2.- I tried the option ‘none’ for not showing the reset button but it doesn’t work. Do you know whats the problem?
