Currently the Base relationship design window does not support any way of using
the schema display beyond this window.

Objects are not available to the clipboard, the display may not be saved as a
Document type, nor is it possible to print the display.

The enhancement would be to allow the layout items in the window to be exported
to a new Draw document, with the tables, connectors and cardinality indicators
added to the draw page of the new document as separate objects.

The motivation for this RFE is to more adequately position Base to the SMB
market, where the ability to document the database structure is considered, IMO,
a baseline requirement.
