Create an enhancement for the Layered Nav so we can filter also the actual product dimensions such as: Length, Width, Height. those can be as a slider, e.g price slider with a step of value 1 or 10 etc the setp value can be also as a setting on the layered nav

This can be done easy by use a function to retrieve the product postmeta values

_length

_width

_height

this functionality is quite necessary as for the shops that have thousands of products is not needed to create additional attributes as a dimension value, also this will improve the overall performance of the site
