Your Amazon widget would be more useful if (1) it didn't take up so much vertical screen space and (2) it offered – either via default or a toggle – the ability to open results in a new window or (in my case) Firefox tab.

Great Idea Philipp. Thanks for being Transparent ;)

Some javascript in the bookmark links does the same thing (in less space):

Mark, I can't control the width (to my knowledge), I can only control the height. I set the height to 90 pixels, but the width is dynamic depending on how you resize this.
