Separate folders for each device backing up to the camera roll
If you have multiple devices that would take advantage of the camera roll there should be an option to put them in separate folders. IE if you have an android phone, ipad, etc each device should be given the opportunity to use a subfolder (Camera roll\ipad and Camera roll\android)
We’re interested in improving the experience for users of camera upload to OneDrive. Looking at better ways to organize and structure the files is an important aspect. No other updates right now.

Going off this, I think the picture backup folder should be customizable on each device. Being able to choose the folder the camera will back up in to.
This way, I can make different folders for my different devices and choose to back up pictures to a different folder temporarily.
For example, if I go on vacation, I can make a folder called 'Vacation 2014', then set my phone and my wife's phone to put pictures in to that folder while we're on a trip making it easy to locate them after we're back.
