Actually, I think this is very good news, don't release it if it is not good enough... Personally I hate the solutions that have been released so far (and I have seen some: JAR, Carenado, FF ), and as expected, a lot of wrong manipulations of the zoom whilst trying to rotate a knob or vice-versa. Click and drag works just fine, simply a matter of adapting to it, after all, most of us are still young enough not to fear a change in habits I would assume.
