I have to say, I'm impressed with the quality of this module and the support behind it.
After installing, I had a problem with the filter system. So I opened a ticket to see what was wrong.
Turned out that my site was loading multiple jquery instances at the same time, and worse all different versions.
So, obviously it couldn't work.
Long story short, Oli fixed it in no time, installed a jquery loader plugin, who makes sure that now my site only loads the latest version of jquery ONE TIME and on top he even did some changes on the css to make everything look slick :)
I really wished that more developers would provide support like WS-Theme does.
So, if you look for a portfolio plugin, look no further. It's worth every cent of it.
