The placement of the Pin It icon was allover the place (sometimes off the image), even though I kept choosing the right alignment in the css section. It also wouldn't add the icon to the gallery images, and messed up the alignment of them.
It also kept adding the pin it button to the social sharing section (I have the share buttons by Lockerz), which was annoying. I noticed in the support forums, other people were having these problems, but they weren't resolved... Needs to be more user friendly!
