Drag-drop tabs from one tab bar to another

As subject says, I'd like to be able to drag a tab from one pane to another pane or even another opus window pane.

You can already do both, you just have to drag them by their icons, not by their labels.

(Dragging the label is like dragging the directory itself while dragging the icon is like dragging the actual tab.)
