Enable ~popper~, a better version of ~popwin~, which might actually work. It groups popups by context and allows you to specify their exact positioning, or even a custom display function. It also seems to be better at restoring the previous layout.

  Add a [[id:db1d0122-58d6-4dec-84f6-afcb52937fc7][consult]] source for popped buffers.

Force user buffer switching to also obey ~display-buffer-alist~.
