I was bored, so I made a very simple UserScript to throw bitcoin monitor into full screen.
If you care to try it, I've thrown it up at my google page.

It just adds a link to the bottom right corner of the page to toggle on/off.
I personally use this when I want more "detail" in a large cluster of transactions.

Any opinions, thoughts, suggestions, etc are welcome.
Thanks for your time.
