Google Docs added drag and drop to file upload page, that makes it easier to move your files into the cloud. Drag & drop is already available in Docs for images. The main advantage is that the new feature doesn’t use Flash or another plug-in, so it should be more reliable.
Now if you’re using Chrome, Safari, or Firefox, you’ll be able to quickly drag files into the drop area and shoot them up to the cloud.
Google Docs also added a menu option “Compact controls” that lets you hide the title bar: View > Compact Controls or pressing Ctrl Shift F (Cmd Shift F on Macs).
It’s only available in the new document editor and it’s probably more useful than the “hide controls” feature from the previous version of the editor.
