Great plugin! I've just installed it and have been playing around with a few settings. One thing I did notice is that the 'Portfolio List - overall width' setting is fixed to pixels. My site is a responsive site and the CSS changes 3-4 times as the browser width decreases.
Is there any possibility that you could have the option to set a max-width in % and ignore the fixed pixel width? it looks great on larger browsers but as you get smaller it breaks outside of my containing box.
See here for any example: http://www.livefreedietravelling.com/about-paul/portfolio/
Any help would be greatly appreciated.
