Extensibility workbench versus designer workbench in the web UI framework

The Extensibility Workbench is used to modify the UI while the application is live and running online. The changes can be saved and later applied to the application EAR, if required. Use the Extensibility Workbench to make changes to part of the UI.

To create new screens while working in the Extensibility Workbench, access the Designer Workbench through the Design new screens link at the bottom of the Extensibility Workbench.

The Designer Workbench is also used by application developers to first create offline the screens that you can modify using the Extensibility Workbench.
