I have implemented smooth movement for dragged items and the dragging sound effects! The implementation was fairly straightforward, but I spent several hours hunting down niche bugs caused by items being able to move now. But, that completed, dragging is done and I'll be checking it off the list and moving back to the website until Pica finishes up the sprites for another content update.

Who knows; maybe items will have other reasons to move in the future and this code will have other uses. Magic Imperial conveyor belts or something? In any case I'm sure people will appreciate being able to drag barrels to the river more than enough to justify all this.
