Would be great if the Chrome tab title changed to alert how many people were looking at the document, OR... that someone has posted a chat. Something that like gmail shows the "unread" number in the tab itself. I'm trying to actually use a Google doc as a website, because it facilitates the online chat. I am willing to leave a chrome window open all the time, and even on that document. But wouldn't it be great if that document would magically appear from beeing hidden to being displayed on the screen IF someone posted a comment in the chat? THAT would make lots of people use a google doc as their actual home page I bet.
