Great add-on for Caldera Forms, however it conflicts with multiple plugins I've got installed in WP 4.4.2:
Intense Shortcodes (Paid plugin)
The shortcodes themselves in the above plugins do still work, however the "Insert" buttons to insert/generate those shortcodes in the editor no longer do anything when this plugin is active.
In the short-term I'll probably disable this add-on whenever I need to add a shortcode using either of the above plugins, however I'll likely have to uninstall this in the near future due to the inconvenience of this workaround.
That said, I do find this add-on useful and will gladly re-rate as 5 stars if this can be resolved.
(As a side note, I highly recommend Caldera Forms itself.)
