Product Filters para WooCommerce

Currently I am using Product Filters for WooCommerce. I can add Product Filter – Attributes as a widget, but it only accepts List, Inline, Select or Dropdown in the style field. Why not add a slider style which picks the lowest value of a numeric Product Attribute and the highest value of the same numeric Product Attribute and creates a slider similar to the price slider.

One of the websites I have created, sells solarpanels and the efficiency of these panels are now shown in a large list of individual numbers. It would be so much easierfor a customer if you could select a lowest and highest value in a slider.
