Always wanted to have more visible, darker, wider, smoother shadows for your windows, tooltips, menu?
Just like Windows 7 Aero Style?
Independent of any custom theme?
Nice Grayscale or even blurred background when having modal windows?
Well, the wait is over. Just implement Extended Window for ExtJS 3.4 (it even works with 2.3!)
Want a demo? Sure http://www.lubber.de/extjs/extendedwindow
Have fun
