Quickly take screenshot of entire node grid at appropriate resolution

You click a button, it takes a screenshot of your entire node grid at a readable resolution and saves it to your desktop. You could even auto-add a logo watermark in the bottom corner.
It seems with these kinds of editors screenshots are the main way shaders are discussed and shared, this would be a slick and useful feature that wouldn't be hard to implement and would help spread Shader Forge around the internet.
