To extend the editorial interface, you can plug gadgets into the navigation panel (left) and assets panel (right) with information related to the content. These gadgets can have a tab on the tab toolbar.

When you create a plug-in for the edit view, the `PlugInAreas` attribute determines the rendering location set by the `EPiServer.Cms.Shell.PlugInArea` string constant:

- `AssetsPanel` – Adds the plug-in as a gadget in the asset panel.
- `DefaultAssetsGroup` – Adds the plug-in as a tab in the asset panel.
- `DefaultNavigationGroup` – Adds the plug-in as a tab in the navigation panel.
- `NavigationPanel` – Adds the plug-in as a gadget in the navigation panel.
