Hi,

– TABS.SLIDER: you can use the other attributes with the key ‘product_order_by’: position, created_at, name, price, top_rating, most_reviewed, most_viewed
– PRODUCT TABS: The producttabs module just support one from CATEGORIES and ORDER BY at the same time. The NEW PRODUCTS is just consider the only attribute CRETED_AT.
– AJAX TO CART: Sorry, we dont have any addon like that. Please do that by yourself.

In the future, if you have some problems please create a Topic for per one.

Best regards,
