I also would love to see this. I already use MS Office to handle my paperwork, but I use OneDrive to handle access from my other devices, especially in the field. I receive a work order in my e-mail, save attachments and revisions thereof to OneDrive in preparation to go on-site, update and collect signatures on-site, then send any results by e-mail to either where I got the work order or the project management. My paperwork I have signed is the most important. While I can directly access documents stored on OneDrive from Acrobat Reader DC for Windows (thanks for that, by the way), I would love to have this for Android.
