Attached views
You can create a development
view that is to be attached to the stream named under Development
Stream. The list under All attached views shows
the view tags for all views that are currently attached to the stream and
whose view hosts are currently running. If you wish to use one of the currently
attached views, clear Create a development view and
the wizard omits creating another view that will be attached to the development
stream.
If none of the currently attached views are usable, set Create a development view to have the wizard create a new view that will be attached to the development stream.
