Google Docs added support for drag and drop uploads, a feature that's already available in Gmail. The main advantage is that the new feature doesn't use Flash or another plug-in, so it should be more reliable.
"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," informs the Google Docs blog.
In the near future, this option could be used to upload folders, not just multiple files. Google Chrome already supports directory upload using the input tag.
Google Docs also added a menu option that lets you hide the title bar: View > Compact Controls. 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.
