Thank you, that helped a lot. Here's my version if anyone is interested...
1) Made the left hand navigation slightly grey to offset so much white.
2) Made the list of articles have less padding (more "compact", less "bloaty" :) )
3) Removed the "Home", "All Items" and "Explore" links (I never use them and just wanted it clean)
I have that issue with the new version of Google Docs. You get just a little more than half the screen to actually write inside the doc. The rest is all "chrome". They should at least make all that disappear and appear on demand.
