It allows you to adjust the size of those buttons in pixel increments (although the size can never be larger than Title Height - Frame Width, so you'll need to adjust those too). Also, "Glow" window decorations will allow you to pick one of a few preset sizes for the buttons, if you absolutely can't stand "Smooth Blend". E. Liddell
