Sometimes you have a "source" document which you wan to export as csv or html - eg because that's easier to be processed by additional tools. It may still be useful to keep the old name so that formatting isn't lost. That's why I suggest doing it the gimp way: provide "save-as" and an "export/save-to" command. The first changes the document's url, the latter doesn't. Yes - this is not a bug - its a feature request
