Tile-o-some is the most handy way to see several pages at once.

Ctrl+N and Shift+click opens a new window next to the right edge of the active one.

git clone git://github.com/NV/chrome-o-tile.git

chrome://extensions/ → Load unpacked extension... → choose chrome-o-tile/chrome directory

Bleeding edge version doesn't autoupdate, so you have to do git pull manually.
