I would love to see this integrated as well! I have been using Posts 2 Posts plugin for a very long time now on dozens of projects and it’s absolutely one of the best WordPress plugins hands down!
However I try to avoid using a lot of different WP metaboxes in the WP admin area for my clients. The Posts 2 Posts adds a metabox for every connection, it would be so cool to be able to add these boxes in the ACF interface with the other custom fields. Could this be possible somehow?
