Windows 7 includes a feature for easily arranging windows on larger monitors - drag a window to the left or right side of the screen and it will be resized to use half the monitor (or drag to the top to maximize). The most obvious use of this is to drag one window to the left and one to the right to quickly get 2 side by side windows.
My question is, even on a 1920x1200 screen the width of a split window is not enough for many applications - in particular web pages tend to be designed for 1024x768 and up. Is there a way (registry?) to change the split between left and right? So that a window dragged to the left will be resized to 60% of the screen, and one to the right will occupy 40%?
