Draggabilly

Javascript library for drag'n'drop that seems to have more options than native HTML5 drag'n'drop.

They also claim to support "multi-touch", which would be awesome if it means that you can drag on touch devices.

Another library with similar aims is interact.js Show archive.org snapshot (Github) Show archive.org snapshot .

They're pitching JavaScript drag and drop, resizing and multi-touch gestures with inertia and snapping for modern browsers (and also IE8+).
