So I just had an amazing idea, what if there were next/back arrows in the main menu for single product pages. So for example look at my main menu here http://wildlatina.co/product/cindy/
now for this single product page, imagine a white back arrow on the left side of the main menu as a button that takes you back to previous page and on the far right side a white arrow button that says next. When you click on next it takes you to the next product, when you click on back it takes you back to the previous page. Options: The buttons would only appear on the menu when user is on single product pages, or option always activated.
The arrows can be fontawesome icons and any color, would be cool. Add icons and word to the buttons.
