Sometimes when dragging dwellers, I might accidentally drop them in the wrong room, or end up cancellng the drag. What can be frustrating when trying to set some dwellers on rooms to stop an incident.

So I though that would be nice if when we start to drag one, a box will appear in the hud that can keep a image of the dweller, to work like a buffer. And can hold 6 of them.

Then we can drag the entirely content of this buffer box to the room of choice, or individually, and the dwellers will start to move from the previous rooms all at once. In case of a room that can't accept more than 6, only the ones added first will move.

This box can be like a "window", with a title bar, that is how we can choose to move all the dwellers, and a X in the corner to clean the info.
