9?

Holy cow. It may have been RMS who said if you are even “four-deep” it’s time to refactor.

It’s a great name for the colors chosen, at least for me. Quite evocative.

(Since you mentioned Prot’s themes… https://protesilaos.com/codelog/2022-10-24-ef-cyprus-theme/ I’ve been rocking for a little while now.)

Have you tried taking that on a plane?

I use:

(add-to-list 'display-buffer-alist
             '("\\*e?shell\\*"
               (display-buffer-in-side-window)
               (side . bottom)
               (slot . -1) ;; -1 == L  0 == Mid 1 == R
               (window-height . 0.33) ;; take 2/3 on bottom left
               (window-parameters
                (no-delete-other-windows . nil))))

(add-to-list 'display-buffer-alist
             '("\\*\\(Backtrace\\|Compile-log\\|Messages\\|Warnings\\)\\*"
               (display-buffer-in-side-window)
               (side . bottom)
               (slot . 0)
               (window-height . 0.33)
               (window-parameters
                (no-delete-other-windows . nil))))

(add-to-list 'display-buffer-alist
             '("\\*\\([Hh]elp\\|Command History\\|command-log\\)\\*"
               (display-buffer-in-side-window)
               (side . right)
               (slot . 0)
               (window-width . 80)
               (window-parameters
                (no-delete-other-windows . nil))))

(add-to-list 'display-buffer-alist
             '("\\*TeX errors\\*"
               (display-buffer-in-side-window)
               (side . bottom)
               (slot . 3)
               (window-height . shrink-window-if-larger-than-buffer)
               (dedicated . t)))

(add-to-list 'display-buffer-alist
             '("\\*TeX Help\\*"
               (display-buffer-in-side-window)
               (side . bottom)
               (slot . 4)
               (window-height . shrink-window-if-larger-than-buffer)
               (dedicated . t)))

That would be perfect on my Hannah Montana Linux installation :-)
