New features added to Google Docs today bring new functionality and broaden the uses of the web based productivity software. The most interesting feature to me is the equations editor. Most of the documents I create have some sort of equations in them, so I'm definitely eager to try this out. I've had difficulties in the past with Open Office and compatibility issues with Microsoft Word, so this could prove very useful. The ability to add subscripts and superscripts has also been added, making it easier for users to add in various chemical compounds. Users can also use the Google translation tool to translate to any of the 42 languages available.
