PowerPoint should automatically allow me to add graphical icons (let's say in
the upper right corner) to a PPT presentation that allow the viewers to see
where we stand in the presentation.  In other words, instead of "page 15 of
60" we see a series of chevrons or some other choosable shape that is 25%
filled in.  You know, a status bar.  They're used everywhere else in computer
stuff.

Can you name it after my wife, Tiffni, who struggles with this every day.  
Call it the "Tiff Tracker!"
