Went pretty well but there is one issue with the Nav bar you can see when clicking the tablet icon in the customeiser or in real life on an Ipad 3 in landscape mode
The cart icon ( and any menu bar items eg. search ) sits outside of the Navigation container. Which is why drops to its own line and cannot be floated to the right of the last menu item when the menu wraps to new lines.
Wouldn’t the Navigation Drop Point be a better solution as it would keep the menu inline across that smaller screen size ?
