Do you miss Google Wave? Judging by the adoption rate of that ill-fated service, probably not. But for those who were fans of Google’s attempt at ... whatever Wave was ... Google Docs has made some practical, Wave-like changes today that you’ll appreciate.

In a blog post explaining the changes, Google engineer Nick Cooper said that the features will only be available in new documents for those users who have the company’s new “rapid release” track for Google Apps.
