You can also change how the docs are sorted or just simply refresh (read: sync) your folder to see any additions that have been recently thrown in there.
In addition, users have the flexibility to choose from seven different RAID configurations for specific hard drive protection preferences, schedule backups, and set file and folder permissions to allow for ultimate sync flexibility and storage control.
Apps can simply ask if you want to sync with Dropbox now and the act of creating and maintaining a folder won't necessitate any further user input (though, it still can if the dev so chooses).
