Well, that is it, really: support for OneDrive as a storage backend would be awesome.
Office 365/student subscriptions come with 1 tb of storage, and onedrive works across linux/mac/windows. Box currently doesn't have a good bidirectional sync client otherwise I would use that. Thanks for your work!
OneDrive for Business connects to the Files app. Although I don't have a clue how this interface works, it looks like a very generic interface. Wouldn't it be feasible to use the Files app indirectly to connect to available cloud services?
This is something I want to look at.
