Over on the OneDrive User Voice forum, a Windows Phone user did suggest that Microsoft ought to make available offline access to files on the platform, which is what the desktop version currently has. Casey Penk, a Program Manager at Microsoft, has marked that suggestion as “in the plans”, although one might have to wait a wee bit more before this particular feature will arrive, since there is no no fixed timeline where its delivery schedule is concerned.
Apart from that, it has been reported not too long ago that OneDrive would be on the receiving end of a music storage feature, not to mention the ability to stream via Xbox Music. Windows Phone users would no doubt be more than happy to hear of such developments.
