When a user has an item selected and then selects a different item, he should be prompted to save any changes that have been made to the current item.

When a user has unsaved changes in an item and then closes the application, the user should be prompted to save the file.

The "Save" buttons and menu items should always be available for items since a user may choose to update a page even if it hasn't changed but because the links will change when rebuilt.

When a domain is selected, only the New Domain and New Group buttons/menu items should be enabled.

The New Item button/menu items should only be enabled when a group is selected.

The View Resources window should hide when a group is selected, and it should be updated automatically when a new item is selected.
