Users who need to customize Emacs don't necessarily need help to find
their initialization files.

Actually, the amount of horizontal display area available on smartphones
tends to reflect that of low-resolution desktop displays and computer
terminals.  Emacs UI currently works well on either.

Nevertheless, each of those items is used frequently enough to justify
their placement there.  ``Open the configuration file'' is not, at least
in Emacs.

inclined to make the latter happen, sorry :)
