Re-pack after dragging

Is three any way to use Packery for sorting items? Left to the right, with fixed width/height?

Dragging seems to work up/down.. so it would not work at all for sorting items.
I would be very useful if the dragging could shift items to the right and cascade, instead of down.

The issue does not name a file, test, or entry point; begin by locating Packery's dragging and packing behavior. Define whether fixed-width, left-to-right sorting with rightward cascading is supported, and establish tests or examples that demonstrate the intended item order after dragging.
