Closing an Addin custom view

[Ian Mitchell]

Having coded my Add-in, I'm finally getting around to the tidy-up of the UI, and I can't seem to find any way to close the Custom View under program control. Is there an interface somewhere to do this ? If not, why not?
Also, having created the new Tab which contains the custom view, how can I change the name of it? In my add-in, the user gets to do a 'saveAs' for the data in view, and it would seem sensible to change the tab name once they have done so.
