WISH: Add button in Layer Panel

Or in the context menu when you select mutliple layers and right-click them.

Currently there’s no way, besides dragging, to move all selected layers inside another layer.

I am not talking about just moving the objects inside the layers but the layers themselves.

If you have a long list of layers drag-drop is useless because when going to the edge of the list the list doesn’t scroll-up (or down).
