Would also like to control which categories are Pinable.
I'd really like to use this, so I'm hoping for these minor changes to earn 5 stars!
Thanks for the review. This plugin has definitely been a work in progress, but this new version (v.1.4) I just put out today has the items you listed fixed.
You are able to set articles or whole categories to not show this plugin. Also the button does not show unless it can find an image in the article (the whole reason for Pinterest are images). So only if the article has an image or a K2 item has an image, will the pin it button show.
I appreciate the feedback man, have a great day!
