Enable viewing of XPS files on OneDrive.com
With Office Online, we have the ability to quickly and easily view Word, Excel, PowerPoint, and PDF documents in the web browser. However, we cannot currently view XPS documents. Many times, I print to XPS to quickly get a portable document that I can share with others, but there's no quick way to view it in the browser. Plus, the Windows 8 Reader app supports XPS viewing. Therefore, I think Office Online should as well.
