I've used your dummy files as mock-ups to play around the theme to get to know it a bit more before start creating something on my own.�

I've tried to create new page with Masonry settings but somehow it didnt work. It shows pages as 4 regular size columns (I'm using portfolio files from dummy file). I've also made settings full width but it leaves empty space on the side ( see file attached). �

OK it seams it didnt render code properly ? :D I went on other page that use same portfolio style and copied code from there into mine and it worked...
