I've had trouble staying focused when using Google a while back and decided to write a Chrome extension for improving the Google Search experience. Here's the URL for those interested: http://restfulpanda.com/post/25658805059/cleaning-google
A big improvement, but as with ad blockers, you still have search results crammed into a fairly narrow box. Obviously, you won't be able to get Google to show longer titles and descriptions, but you should be able to widen the box so that the two-line descriptions end up on one line, which would fit more results on each page.
I just wish you could get it to expand rightwards and get the longer descriptions back, the amount of space they've wasted to 'integrate' G+ really annoys me.
