minibuffer at the top

[Suno Ano]

By default the minibuffer window is at the bottom of a frame (other
windows on top the minibuffer). Is it possible to put the minibuffer at
the top (other windows below)?

Having a separate frame[0] for the minibuffer is not an option. From my
point of view, there should be some option to put the minibuffer window
at either the bottom or the top of the frame.
