I finally saw it -- the posts went flippy-flip right under my mouse!
yes, I DO think that a 'stop' button (that's 'wwt' for our Qc friends ;-) ) would be a very cool idea. You sold me on this one.
Could we consider begging for a slow-scroll thing too, so that when there's X new posts, it'll slow-scroll up/down and insert-sort them as required? It's almost as jarring as the flippy-flips, but it'd add the one at a time at a constant rate instead of the crushing block, which may be slightly more pleasing to the eye.
... because yeah, all the other issues must be fixed so I can bring up silly chrome and polish? :-D
