What it does:
1. ) Adds (5) additional product listing page product filters (Color,Size,Weight,Height,Length)
Don't worry, you choose your filters, name them anything right from admin!

2.) Each product filter can be assigned unlimited filter terms.

3.) Assign each filter term right from the admin>product_info page

4.) Tested with "easy populate" so all product filter terms can be added, changed and deleted in bulk.

5.) Admin option to show/hide filter terms "product count"

6.) Admin option to exclude Filter Side-box at category "1" or sub-category level "2_3"

Any suggestions?
