Thanks, that helps.

Is this documented somewhere?

Is there any way to change an existing map?
  I see "New" and "Duplicate" but neither "Edit" nor "Delete".
  This could lead to irreversible accumulation of cruft.

Is there any way to get control of the outline color
as distinct from the fill color? About 99% of my plots
use open symbols, i.e. a visible outline but transparent
fill.
