First, collaboration just got more convenient with the ability to create shared folders. Next up, you now have the ability to upload multiple files at the same time. This could be a real time-saver when you have a group of documents to send to the cloud.
Shared folders have been the most requested Google Docs feature for some time. Happily, they work just like they should, letting you set the same level of permissions to your collaborators for all documents in the folder (including edit and view-only access levels). If you have a group of files you need to share with the same group of people, a shared folder can simplify giving everyone access.
Multiple file uploads is also an easy process. From the upload page, simply use "shift" or "CTRL" to select multiple files in the upload dialogue box, and when ready click "start upload." Progress bars have been added so you can get immediate visual feedback on how the process is going.
