I just installed beta3 on one of my machines, and most everything seems rock solid. The only thing that I'm missing is a feature I'd noticed and liked that I first saw in the alpha series (I'm running alpha7 on my other box) -- being able to shade a window using the mouse wheel.
Has this feature been removed from the 0.65 series? (i.e., did it accidently creep into the alpha and was later removed for addition in 0.70?) --Matthew
