Multi-platform cloud storage app Dropbox has updated its web interface today so that any changes made from other browser instances or apps reflect almost instantly. For example, renaming or moving a file using one of the company's official client apps will show up in a split second in the browser. File changes are already reflected immediately on the PC and Mac clients, so it's nice to see Dropbox bringing its web interface up to speed. While this isn't as significant a change as the recent rethinking of shared folders, a snappy web interface is sure to please the Dropbox collaborators out there.
