When you have hundreds of folders, (navigating a network and moving files) this can be a real pain in the butt.
Scrolling in this folder is so finicky, it's actually hard on the wrist to navigate because you need to be so gentle.
This wouldn't be so much of a problem if the scrolling issue in the folders pane was fixed in the first place (jumping/scrolling 13x too fast with the magic mouse). Since these two problems exist it makes it even more annoying.
