I need following modifications of Prestashop 1.4:
1. Module sitemap to generate different sitemaps for diffrent language + to function with cronjob module
2. google base module to get to work with cronjob (together with already done modification of langugae/tax choice)
3. Product Filter module modify in order to work with drop downs in stead of with check boxes (can be selected from backoffice) for every filter option (category, manuf, features, etc)
4. An option by a customer can choose if prices will be displayed with taxes or without taxes.
