Non-looping Behaviour?

[black-eye]

How do I achieve non-looping behaviour (sliding stops when I reach first or last image)?
Original Slick Slider has a parameter infinite: false, but it doesn't seem to work for the lightbox.

Hi, are there any plans on resolving the issue? Or at least some advice, how to do it?
I know, this is not a support forum, but since it was labeled as bug, I'd like to believe, there's a will to repair it.
Thanks.
