I miss a function of the OpenOffice Presentation. Similar to page count in the
word processor I would like to have a "slide count" in the presentation module.

Reason: In a seminar on presentations our trainers told us that it is very
useful to provide the audience with an idea of how far the presentation is and
how long it will be. One suggestion was to insert the slide number as well as
the slide count. I can insert the slide number but not the slide count. Now I
need to insert on every slide the slide count - and to change the slide count if
the number of slides in my presentation changes
