DnD with line drop indicators

[willwang888]

Hello! Thanks for all of the amazing work on this library by the maintainers. Has anyone had success in building a DnD experience with vertical drop indicators that doesn't use other libraries?

I'm specifically looking at something like this: https://codesandbox.io/s/react-beautiful-dnd-react-virtualized-forked-c7sm5b?file=/src/facade/draggable.tsx

Or something like this: https://codesandbox.io/s/spiking-auto-gap-less-assumptions-o6yw9f

These examples both depend on the @atlas-kit/drag-and-drop libraries which seem to be in early access & are not guaranteed API stability. Does anyone have any thoughts / success on building out these indicator placeholders with just the props provided by the library, or can provide some pointers on how to go about it?
