Thank you for everyone who has been providing feedback on this thread. There is a variety of work happening to make it easier for people to save to/from OneDrive and SharePoint. There are no specifics and ETA’s to share at this point.
Thanks for your feedback! Just a note to let you know that we’re building your suggestion now. We plan to increase availability to this feature as we continue improving the tech, and ensuring a smooth experience across Office 365 following the URL changes in SharePoint Online.
