>I like new design but with my screen resolutin 1152x864 there's to much screen real-estate wasted (filled with background image) on all sides: 1/2 inch on the left, 1 inch on the top and 4 inches on the right.

I'll take note of that. We'll, later on, probably release minor enhancements to benefit of about 1.5-2 inches more, no matter the resolution.
