This is a suggestion regarding the six on a page handout.

I often flip charts for presenters in meetings, and I use the six on a page
handout for a quick reference.  I'm not interested in content, but rather
slide titles and page numbers so I can easily jump to a different slide if
the presenter asks.

However, the page number on the handouts can be sometimes hard to read--or
in some cases, the creator of the presentation forgot to put it on the slide
altogether.  That makes it very difficult to figure out what slide to jump to
(especially if some of them don't use title placeholders like they're
supposed to).  It would be handy to have a quick reference handout with the
page number printed in gray and large in the background of each slide--sort
of like what Excel does in its page break preview.
