When several cards are selected in a kanban they should move together

Received feedback from a user, he selected 3 cards and was frustrating that when he was trying to drag and drop them, only one would move.

This doesn't seem like an easy problem to solve but logging it.

Would also be nice to shift+click to multi select in the app
