Moving a leaf to another container
I am in this situation, where the "desktop container" has four children (leaves):
- Window One
- Window Two
- Window Three
- Window Four
How can I make it have two children, having Window One and Two inside a Vertical split, and the same for Windows Three and Four?
With pictures, I want to go from this: Picture 1
to this: Picture 2
Making Windows Two and Four floating and drag'n'dropping on the titlebars of One and Three would be a nice feature I suppose.
