Next/Previous Controls on Responsive Version

I know this is free, so we can only complain so much. But as others have pointed out, the lack of next/previous controls on the responsive version is really frustrating. Right now I can’t use either of your plugins; the old version isn’t responsive (and seems impossible to do myself because the js values override the css), and the new version doesn’t allow the user to navigate with the thumbnails hidden, which is what my client requires.
