There is an issue with the css files, when setting a view to scroll vertically all the items squish together.

The problem seems to be with this line of css in the jquery.symplyscroll.css: 

.simply-scroll-vertical .simply-scroll-list li {
height: 35px;
}

it should be 

.simply-scroll-vertical .simply-scroll-list li {
height: auto;
}

this can be fixed with custom code in the theme stylesheet but the module shouldn't need any extra styling (IMO)

btw, I really didn't know the best place to put this issue so feel free to move it if you find a better place
