As you navigate through categories, a bread crumb trail displayed at the top of the UI will enable you to jump quickly to higher-level categories. Selecting a category will show all Plugins in that category as well as Plugins in any sub-category. You can browse categories of Plugins using the tree interface on the left. This interface displays all of the Plugins that are currently installed and can enable or disable Plugins individually. The Plugin Editor is accessible from the main 'Window' menu. You can see which Plugins are currently installed by opening the Plugin editing interface from the Edit menu. If you want to jump right in and create a Plugin now, please see the Creating New Plugins section. Many existing UE4 subsystems were designed to be extensible using Plugins. Plugins can add runtime gameplay functionality, modify built-in Engine features (or add new ones), create new file types, and extend the capabilities of the Editor with new menus, tool bar commands, and sub-modes. In UE4, Plugins are collections of code and data that developers can easily enable or disable within the Editor on a per-project basis. This page describes the development and management of Plugins for use with Unreal Engine 4 (UE4) tools and runtime. Distributing a Plugin on the Epic Marketplace
