Yeah, sorry about that but thanks you asked. I am trying to integrate rollApp (https://www.rollapp.com/), Microsoft Office online and Yandex document viewer into it. rollApp supports literally hundreds of file formats. The only problem I have is keeping the interface less complex. For that I am now working on a API wrapper interface separated from the extension to keep the extension's settings simple. It may take a couple of months before I roll it out though.
