+### Perspectives for fast switching of the complete main window layout
+A perspective defines the set and layout of dock windows views in the main
+window. You can save the current layout of the dockmanager into a named
+perspective to make your own custom perspective. Later you can simply
+select a perspective from the list to quickly switch the complete main
+window layout.
