It would be extremely useful to have parameters to save the positioning and size of an OpenDocument format document.
(4 parameters = position horizontal, position vertical, size horizontal, size vertical, preferably in reference to top left corner)
This would be a per-document parameter.
(Excuse me if it already exists, but I couldn't find such parameters in OpenDocument 1.1, nor in OpenOffice.org 3.0 or previous versions.)
