Please (PLEASE!) make row animation optional

[RogerWilco]

I saw the dialog when row animation was suggested. The coding effort to implement this must have been heroic and in most circumstances it's a work of art. However I prefer to sort my transfers by activity and with a handful of transfers seeding concurrently then the effect is quite literally nauseating. The rows jump around continuously (as they always have) but now with the animation it's impossible to even watch this. As a side issue, it takes around 10% of one cpu on my fairly fast Mac Pro just to do the animation. If you don't believe me, just try it under the conditions I mentioned.

Please make the animation optional or (even better!) average the activity over a longer period so the rows aren't continuously sliding around.
