I'm not sure everyone would like it -- it's like 'hot tracking' that I found in some old Solaris systems years ago: the keyboard input went to whichever window had the mouse in it. I actually found that to be really annoying as I often bat the mouse cursour out of the way when it's over text that  I'm reading, but I still want the text cursor to remain there for keyboard input (including scrolling).

 

If you find changing OS jarring then just stick to one or the other and stop shilly-shallying around! Tongue Out
