Plugins are included with normal applications. If they're packaged with an application, they'll show up in a list on the application's install page. See Installing Templates for more information.
Specific plugins can be disabled even while their applications are installed.
- Open your organization's Management panel.
- Click Plugins in the menu bar at the top. If you don't see it, you don't have any plugins installed.
