I have found a strange z-index problem on my site.
When I click on a thumbnail the large image shows up as I think it should. However, the z-index layer doesn't seem to be sufficient to make the wrapper on top of the site. The images are appearing behind the navigation and search bar in the header of the modified 2012 template. I've tried changing the plugin's z-index but it doesn't help. Is this something that can be changed in an update? I wasn't sure if I should go and try to hack the template z-index next.
Otherwise the plugin seems to be working well.
However, I was wondering if the inclusion of arrows to go to previous and next portfolio items is a possibility for a new feature?
