I’m using Plus Minus, a Chrome extension that lets you select which Circles show up in your Google+ Stream (from your home page), allows you to easily mark posts as read, and offers a wide-screen view so you can see more content without scrolling.
I don’t have the wide-screen view showing for me, as I use the Usability Boost for Google Plus™ extension, as well (http://goo.gl/y6KVc).
