With version 2.0 of Dropbox, users can share files with one another using a link from the Desktop menu. File sharing notifications are sent out in real time, to the desktop application and the iOS app.
Introducing a shiny new feature: a new tray popup that combines the old tray menu features with a timeline of the most important sharing events in your Dropbox. For instance, if someone shares a link with you, you can now see it immediately!
Moreover, if someone shares a folder with you, you can now accept or decline the invitation directly from your desktop. Not only are you notified of these events in real time, but you can easily get to them later. Also, files recently edited are made available so you can easily view or share them.
The interface has been updated to facilitate the simplified file sharing process, adding the ability to accept or decline invitations to files and folders via the desktop.
