Yr plugin is an awesome gadget and it plays nicely with WP 3.6.1. Just great, thanks! However, I have an issue similar to the one of the previous poster. Instead of ACF, I use Matt Gibbs' (also very nice ;o) CFS plugin. Unfortunately, all meta boxes created with and managed by CFS now occur on every tab of the corresponding post type's edit page. Any chance to get that fixed/patched?
