I would like to adjust the threshold that determines whether I am pressing a button or dragging. I find that a number of times I try to press something on the home screen it is interpretted as a drag. However the drag is only of a few pixels. Clearly not a worthwhile drag! I'd prefer to be able to say "if my finger wiggles only a few pixels still consider it a press."

Is there such a sensitivity configuration available? Perhaps some magic gconf parameter of GTK or hildon?
