Couldn't you just hide the widget until all the items have been added and
then show the widget once added? Saves a bunch of redrawing (or so I would
imagine).

Removing the "elevator" sounds like a particularly bad idea to me.
Especially if you're talking of a list of thousands of items. Who wants to
scroll 1 item, or even one page, at a time through a huge list to find one
item?

Click(elevator)-drag(to the correct place)-release
As opposed to
Click(pagedown)-hold-hold-hold-hold-release then click(pageup) then
click(itemup)-hold-hold-hold

You could add a kind of double-arrow button to allow the widget to scroll
down a whole page rather than one entry. I think some well known office
products use methods like this for scrolling a page at a time.
