First, thank you for your incredible and very helpfull plugin.
My question is: Can i use the variable %cat_id% from a custom file template?
I've already added this sentence to my "models.php":
'cat_id' => __('The category ID', WPFB),
==> the result is that i have the variable in the list of variables to use, but it is always null!!
can you help me? ^^
