If you look at Swipebox’s current implementation, the close button is in the top right. Ideal.
This plugin currently displays it at the bottom. On Android devices, it looks very confusing due to Android’s soft key icons getting mixed in with Swipebox’s close button. [Screenshot]
If you look at design patterns, the close button on any lightbox or modal is usually the top left or right. Therefore, the user is already accustomed to its placement.
Perhaps swapping places of the title and close/navigation buttons?
