Currently, the available plug-ins are reserved for the paid version of the tool, created in recognition of all the project's financial supporters. These exclusive features will be released from time to time as they are requested by the paying audience. These features were developed, in the first place, to validate the new plug-in API, and, of course, to add interesting features to pgModeler to make it even more productive expanding the usage possibilities. These extra features are explained in the next sections.
