The biggest challenge for a content management system is to make it really easy and user-friendly for the editors to manage web content. Within pimcore almost all editing is done by using the drag-and-drop features of the rich administration interface, which is powered by well-known ExtJS framework. Everything else is done with the help of a sophisticated context-sensitive navigation.
Other highlights of the intuitive administration include a multi-tabbed interface, where multiple documents can be opened concurrently and the easy-edit-mode, where you can browse and edit within one single interface.
