Gives your store the bottom navigation bar shoppers already know from every shopping app. Up to five destinations — home, categories, search, cart and account — sit within thumb reach at the bottom of the screen on phones and tablets, and disappear entirely on desktop. Each item can be switched off individually in the admin. The cart icon carries a live count badge that updates the moment something is added, without a page reload: the script watches OpenCart's own add-to-cart request rather than depending on a particular theme's markup. Tapping Categories slides up a sheet of your top-level categories pulled straight from the catalogue. Icons are inline SVG (no icon font to load), and the bar respects iPhone safe-area insets so it never sits under the home indicator.
