It's not a huge update, but today Dropbox gains the ability to automatically save your computer screenshots. Next time you immortalize that Gchat, your screen-cap will be saved to your Dropbox account and copied to your clipboard as a link for sharing. (You'll have the ability to opt out of this new feature, should you feel so inclined.) In a nod to Mac users, the cloud storage service is also adding automatic iPhoto imports. Dropbox has supported automatic photo uploads on Mac and Windows machines for some time now, but today's new feature lets Mac users copy over all locally stored images -- no SD card required.
