Ability to export all text at once, for translation
Please make a way to export the text for translation and then import again. Like InDesign's IDML files. You have so many users that would like to translate their content for foreign language markets and no good way to do it with InDesign.

It is not exactly the same thing you want, but I use it often for same purposes.
