(now it's only one big square for all). - Last 2 Categories : ("Macérats de plantes unitaires" et "Macérats de complexes de plantes"), put them in a blue rounded square separated of the others - Add mention "Origine / Qualité France" + Frech flag on the bottom Footer : - Suppress all social networks : "Tweets / Follow us / Facebook" - Instead put the green links now located on the very bottom - Suppress "Promotions / Nouveaux produits / Meilleures ventes" links Category pages: - Sort by price, then by alphabetical order. now it's only alphabetical. - Add pagination to the top and the bottom (now it's only on the bottom) - Correct the graphic bug on the sidebar (partially hidden) Product pages : - Rename "fiche technique" by "Définition" ? - Put the price and the button "Ajouter au panier" under the picture ? - Allow more characters in the summary field (now it's only 400 characters) - Correct the graphic bug on the sidebar (partially hidden) Generally: Remove the yellow and the black and replace by blue
