Great plugin mate!
Do you think you could you add a social profile for instagram? It's highly popular now, and easy to implement. I modified the plugin by eliminating the google+ field, but I also need google plus :P
On your screenshots, I see the icons for the social profiles are circular. When I installed the plugin, mine appear to be squared... is that normal?
Lastly, the tabs on my install stretch to the width of the profile box, and they are sitting on top of each other. In your screen shots, they are shorter and side by side.
