Customize Shopfiy-theme

1. Make 4 lines in the footer, including the newsletter, making it look nice 2. In the "in-line feature", we want the headline and the picture to be actionbuttons instead of the "press here"-action button? 3. On the shop-site (/collections/all), we want the site to show the products in this order: The collection called singles incl. the headline The collection called sets incl. the headline The collection called accessories incl. the headline So the page would look like this: [login to view URL] 4. On the productpage, we want to include additional productinfo underneath the product. This can also be seen on [login to view URL] The ingredients changes from product to product, so the pictures and text should be changeable?
