+This extension allows hiding all codecells of a notebook. This can be achieved by clicking on the button toolbar:

+![](hide_input_all_toggle_codecells.png)
+
+Typically, all codecells are shown with their corresponding output:
+
+![](hide_input_all_show.png)
+
+Clicking on the "Toggle codecell display" toolbar button hides all codecells:

+Internals
+=========
+
+The codecell hiding state is stored in the metadata `IPython.notebook.metadata.hide_input`.
+If it is set to `true`, all codecells will be hidden on reload.
