Interchange allows you to add fields at any time; there should be
no side effects. You can structure it however you want....

No, the UI is flexible in that regard. You can set the Knar value
UI_ITEM_FIELDS to determine the fields to display in the item editor.
(UI_ITEM_BREAK determines where the lines between sections go, setting
the ui_break_before variable).

In addition, you can make flex_editor calls such as found in 

<A HREF="[area
		item_id=[loop-data userdb username]
		page_title=Customer: [loop-data userdb fname] [loop-data userdb lname]
		ui_data_fields=username company fname lname address1 address2 city state zip country email phone_day phone_night
		ui_return_to=mv_arg=[cgi customer]
	]"><u>[loop-data userdb fname] [loop-data userdb lname]</u></A>

This URL calls the database editor with the named fields in ui_data_fields.

At any time, you can copy pages from lib/UI/pages/admin into the pages/admin
in your own directory to make custom versions that override the distribution
ones. You only need copy the page you want to override; the rest are automatically
picked up from lib/UI/pages.
