Category name in meta title

Hi,

Two seo issues in 4.0:

1. All the categories from the add-on have the same title: “Category …. “
   This leads to duplicate title meta attributes and has negative seo impact.

   Could you add the category name in the meta title for each category page?

2. You should use clean url’s for the filter options: active, popular, …
   parameters like ‘?a=..’ also leads to duplicates.

Thank you for looking into this,
