Yes. Drag & drop actually works right now for one thing in the Whisker
Browser... you can drag methods from one method category to another.
This functionality was basically inherited from Bob Arning's BobsUI stuff
(see http://www.charm.net/~arning/ ). Both BobsUI and Whisker use the
IndentingListItemMorph as part of their hierarchy widget, and so does the
Object Explorer, so the basic drag&drop capability is in the base image
(with the hierarchy-widget-related code), but it's not currently used.
On a related note, I was thinking that I might give a short demo of
Whisker at SqueakEast. I should have it somewhat closer to a working 1.0
version by that point. (For more info on Whisker, see
