Also, please add a shadow tot he header navigation. 2) In the search results page, please remove the left column, and change „Search Results for“ to „Suchergebnisse“, and „It seems we can’t find what you’re looking for“ to „Keine Suchergebnisse gefunden“. 3) On all products listings/categories, please move "sort by" and "show all products" to the top left, move "number of products", move pagination to the top right, and change the product on hover icons as shown in the screenshot (wishlist, new, sale), and display product title and price as shown in the screenshot. 4) On the product details page, please add VAT info ("inkl. X% MwSt."), fix quantity price update, move all share icons into a dropdown called "Teilen", move products details into (closed) toggle boxes and rename Description title to "Infos zum Produkt" and "Additional Information" to "Produktbeschreibung".
