Hey Luke,
Probably not what you want to hear, but you simply need a bigger monitor to do detail work.
I have no problem with the screen real estate in X, in fact I like the layout.
Here's a grab of what I'm editing right now, with scopes on and on a 27" monitor. At 76% of a full 1080 image it's larger than the image we'd be grading on a 14" or 17" broadcast CRT.
Here's the project without scopes and it's a nearly full 1080 image to work with.
The 13" can be a great production tool but it can't be an all-in-one box given the size. Add a second monitor and you're in business.
