We love the box.com integration as far as being able to have Box.com be its own Tab in the Project and Task window and use the native box.com interface to manage files without using up SF storage space.
One major improvement would be allowed to turn it off for projects and leave it on for Tasks, or vis versa in other user's business cases. This would greatly reduce files being uploaded to the wrong object and direct user behavior as desired by management.
Per a TaskRay support agent (Request # 505), Box.com for TaskRay has to be turned on for both to work. If one of the VF pages is removed, it breaks the plug in and requires an uninstall and reinstall. This flexibility would be great.
