Alpha 4 questions so far

Alpha 4 questions so far

Hi,

great to see another release.

a few questions so far:
data-nobackbtn="false" doesn't have any affect, the close button still appears, I'm currently working around this by removing the <a ref.

This is more an idle curiosity, why are there two tick icons in the icons-18-white.png

other than that, upgrade seamless so far

regards

Matt
