I was typing away at something recently an noticed, for the first time, that there was a tab ruler on the top of my page. After some investigation, I found that Google is going through a comprehensive upgrading of Docs and spreadsheet. I noticed some differences between the regular Google versions, and the Google Apps for Education version, but it seems that many of the changes are for both. Some things that are here or coming soon are full tab capability, more advanced headers and footers, real-time collaboration (you can see the text as it is entered), chat on any document, and a lot more capability for inserting images, HTML, etc. I am going to play with it all a bit more and report back with what I think it will mean to day-to-day users.
