Joomla only
Allows you to include a form from an external form plugin into the tabs of the property details. Set the Plugin shortcode to something like 'rsform' and add extra arguments as needed. Doesn't need to be a form, can be anything that's called as a mambot/plugin, but a form would be a typical use. Adds a new configuration option to the Jomres administrator area where you set arguments that would normally be called in an article by doing something like {rsform 1}.
This can be really useful if you want to take advantage of a Joomla plugin that offers shortcodes to it's own functionality, it effectively allows you to import other Joomla component functionality into the Jomres property details tabs.
