Currently this is still in beta version and so there are some limitations such as incapable to handle graphics, images, tables as well as footnote. Anyway, it works great with any plain texts and more importantly, it is able to highlight the differences and allows you to accept, reject, hide the suggestions or move to scrapboard. The delta will be highlighted in different colors and click on the highlighted box will update the text accordingly. That is not all, you can even highlight the change in Bold, Italics font or underline it while moving the comment box away from original texts to make it more systematic and easier for viewing.

Once final edition is done, the updated version can be saved as local copy to be sent to the peers for final touch up or further processing.
