It's a good idea to enable --export-id to enable it to unhide the specified objects if they are hidden. For that, all you need to do is SP_ITEM(object)->setHidden(false).

Right, so it makes sense to add --export-label which would work exactly the same as --export-id except take a list of labels instead of list of objects.

Thanks for pointing me in the right direction. I'll see what I can do with the 0.43 release, but would it be easier for me to look at the latest code in svn? And if so, is there anon read-only access to svn?

Thanks again, Martin
