DockBarX 0.42 is released, this version comes with some improvements and a new feature codenamed "ScrollPeak" : " With ScrollPeak instead of rising windows while scrolling, the windows will simply be opacified one by one until you found the one you are looking for and when you move the mouse cursor away from the group button it will be raised. Nothing revolutionary but it should improve the work flow for some of you."
