OneDrive Temp Sync and Edit
Box currently has a feature called Box Edit that allows you to edit any type of file. It temporarily downloads a file to a cache location, it uploads the differentials every time the file is saved, and it the deletes the local copy when the local cached copy is unlocked (it is closed).
This feature should work with OneDrive, OneDrive for Business, and SharePoint document libraries.
This is huge for non Office files. Office files already work great, but think about CAD, Images, etc.
