Folders - allows better organisation of files within workspaces, chopping up files into directories for later looking over.
Copy/pasting - moving files from one workspace or folder to another simplifies downloading to the desktop and uploading again.
5GB storage - up from 500MB which was little to nothing, especially with the amount of lecture notes the average student has. This will be updated over the next few days, according to the program manager.
New languages - support for Eastern Europe including Hungarian, Romanian, Ukrainian and Latvian.
The new features have already improved the academic lives of one student at the University of Washington, which can be seen in the video below. Using it for research, along with the ease of use and sharing features, allows simplicity of collaborating.
