I must say that the Sections stack is a beautiful implementation of a full page scrolling site and to include this as one of the many stacks in an add-on pack is amazing value. It looks perfect and ready to go with default settings and is intuitive to setup.
A couple of extra settings to hide the side dots and Slide nav arrows would release much needed screen size on mobile. The biggest issue with these type of sites is reducing the content and hiding content on mobile. They work best on tablet up but need careful consideration on small screens.
Also a way to resize, hide and alter the colour of the Slide side arrows is also really needed. The relatively huge arrows can easily encroach over the content on mobile screens.
