Thanks for your participation. Please note that I've unmarked this as a question and added an additional Product Enhancement category to it.
Right now we do not have any area specifically dedicated to ideation. We are considering how we want to support such ideas in the future. For the time-being, any such ideas can be given the Product Enhancement category.
I'm a bit confused about this discussion, as I would expect the change-tracking feature to be associated with successive versions of content-generation, whether such content be a page, article, document, or discussion ETC, and not dependent on whether such content was generated with a rich text editor or a poor text editor.
