redux-form allows a form in any react component to use the redux store as it's storage location for input values. We use it during OAuth.

react-dnd

This package allows us to declare a component as draggable or as a drop target (or both!). This is different from react-grid-layout because the dragging functionality is not restricted to a grid. 

react-dnd-html5-backend

react-dnd can interface with a couple of different drag-n-drop api's. This is needed for the difference between using a laptop and using a touch device (like a phone or tablet). This particular backend is for laptops/desktops, and should not be expected to work reliably with touch devices. If we want to include support for that, this backend can be substituted for a different appropriate backend that supports touch.
