[Infusion-users] Unbounded Scrolling when Dragging Movables

Hey all,

Good idea. Exposing the options we pass to ui.draggable makes a lot of  
sense to me. This is something we've done in other components, such as  
UI Options' text field slider. Makes it easier for users to customize  
our own use of jQuery UI widgets consistently.

In the meantime, will it require a source-level change to the  
Reorderer to implement dragging boundaries?
