Are people who want to customize Emacs likely to use the
Options->Customize Emacs menu?  If yes, why not have this one
additional item there?  If no, why do we have that menu at all?

The tutorial is not the place to explain _where_ Emacs finds the init
file.

So we are now using a smartphone as the reference platform for making
UI decisions?  Smartphones might need a whole new approach to the
Emacs UI, and a bunch of very different UI decisions.  They should not
dictate what our UI looks like on desktop and laptop machines.

When did you last look at modern word processors and their tool bars?
They are, in fact, much more crowded than ours.

We decided it would be a good idea long ago, and are since waiting for
Someone™ to actually make that happen.  IMNSHO, this is more important
than having Emacs run on Android (hint, hint).
