This is out of scope for detached views.

We could work around this by re-activating the "New Window" menu entry, which opens a new workbench window which can be used to arrange views arbitrarily.

But then, I guess, the other window would have its own menu bar, tool bar, status bar and so on.

That's not good for us.

You are right.

I looked around a little bit more and maybe it is not that complicated at all. Reopening for further investigation.
