Customizations for the WorldServer user interface
By using the customization SDK, you can develop user interface elements for various scenarios, such as adding a button on the ribbon, having a dialog box displayed, or customizing a task completion screen.
From a technical standpoint, you can add a customization anywhere on the WorldServer user interface. However, doing so without a customization SDK would be difficult and not recommended. As time passes by and the user interface changes, the customization SDK helps you to manage your own customizations and to maintain a certain level of consistency with the standard WorldServer interface.
