Redirect MS office applications (Word, Excel, Powerpoint) to the online version
When I open Word files using OneDrive for Mac, they open as local files, causing me to lose out on functionality that I would get if I had pointed Word directly to the online file (such as the ability to use the Share menu to share the file or collaborative editing capabilities).
Were I to open the same file from within Word by selecting Open, then going to my connected OneDrive account (not the local folder), then finding my file, I would get all of these nice online sharing features.
While I've only tested this with Word, I'm guessing that other Office365 apps (Excel, Powerpoint) have the same issue.

This is a pretty big issue in the current version of Office365 for Mac. On Windows, you can directly open a Word/Excel file that is stored in OneDrive or Sharepoint and it automatically recognizes it as such and enables Autosave and Co-authoring. On the Mac, it is opened as a local file, without the additional features. The only way to use Autosave /Co-authoring on the Mac is to open the file from "Online Locations" within Word/Excel or by going to the OneDrive website and opening the file from there.
