User Interface Components
The IntelliJ Platform includes a large number of custom Swing components. Using those components in your plugins will ensure that your plugin looks and works consistently with the UI of the rest of the IDE, and can often reduce the code size compared to using the default Swing components.
Please refer to Writing short and clear in IntelliJ Platform UI Guidelines on writing UI-related texts.
The following components are particularly noteworthy:
Menus and toolbars are built using Actions
Tables (TableView) (TBD)
Drag & Drop Helpers (TBD)
