I'm looking for guidance on how to use ELKJS in combination with a custom drag positioning.

I'm the author of https://reaflow.dev which uses ELKJS under the hood for its layout engine. One feature I would like to add is the ability for a user to drag a node to a new position and it stick there while when adding new nodes the rest of the layout stays the same.

I realize this is outside the scope of this project but would love to get the communities ideas on what the best way might be to accomplish this and keep all the power of elk too.

Thanks!
