I find that I am using Google Docs a lot more these days. A major annoyance is that the Google logo and other useless tools take up space from the page, so I came up with the following simple bookmarklet:
Just grab the link with your mouse, and drag it to your bookmarks bar. Click on it when you have a Google Docs page open, and it will hide / show the extra stuff on top of the page.
Note: You may have to resize your window once so that the text area expands, press F11 to do this quickly.
I don’t understand why this isn’t included as a default feature – it used to be supported in Google Docs as a menu option.
