Legit question :) so we've worked on a few ideas since we've been accepted to YC, one of them was the document editor for pharma.

After working on that for a while, we've decided to shift focus and work on the DOCX angle. We felt there's a big opportunity here since .docx is such a widely used format.

As to the feature complete point - I agree. We already cover the most common features today (paragraphs, lists, tables, tracked changes, header/footer) and we're working hard on implementing more. Our main focus right now is to be the most accurate, cheapest and fastest solution out there for common scenarios.
