This means that notmuch commands obey display-buffer-alist so the user can customize how buffers show up. It also permits the use of C-x 4 4, C-x 5 5 and C-x t t, available in Emacs 28. For example, one can use C-x 4 4 M-x notmuch-jump-search RET to open a saved search in another window rather than the current window. Or in notmuch-search mode, C-x 5 5 RET to view the message at point in a new frame. notmuch-tree has custom buffer display logic, so bind display-buffer-overriding-action to make pop-to-buffer-same-window behave exactly as switch-to-buffer while that function is running.
