When I set my carousel (dynamic) to have wrapping mode "None", I do get wrapping from last to start, but not exactly to the beginning of the carousel (about the second node). Clicking 'prev' button on the first element does not seem to do anything, but actually creating nodes with negative indices..
The attached patch solves the "Wrap:none" issue for me.
I must add that I also have prblems with first to last, last to first wrapping.
'both' wrapping works fine for me.
