When clicking on the "structure" link/tab for a view, you see the structure of the result-set.
It would be useful also to see the view definition.
This can be obtained from the information schema in views.view_definition
For bonus points(!) make this editable. e.g. allow the user to edit the defintion, and then execute it by prefixing "CREATE OR REPLACE <view_name> AS" to the definition.
