To get what you want, customize the variable
outline-minor-mode-buttons to swap the two sub-lists in the default
value.

> 1. $emacs -Q

> Buffer navigation arrows are emojis.

I see nothing wrong in the default behavior, FWIW.

These are your opinions, and you are entitled to them.  But they
aren't necessarily absolutely true.  The important part is that this
should be easily customizable.  I don't think we are there yet, so
some work is clearly in order.  But not necessarily to change the
default.

Thanks.
