Add local Mac support for Auto-save
In earlier versions of Office for Mac (e.g. 2011) the auto-save function saved a copy to wherever on the Mac hard drive you desired - either a native folder, or iCloud or DropBox. Then 2016 and Office 365 came along and slyly required you to license OneDrive in order for this function to work. FOUL PLAY! Make it work on the native hard drive and other (more popular) cloud file-sharing services again.
