PL/SQL Developer functionality can be extended with plugins. Documentation and plugin development examples are distributed with the application.
On the application website, plugins developed by Allround Automations and third-party users are available for download.
The third-party rrProject plugin adds its own helpers for writing code and navigating through it, a multifunctional search at the IDE, and other extensions.
