Changing parameters in running EXE slideshow

[FrantaR]

I think that would be very nice feature (not seen anywhere) to have a possibility to change slideshow parameters (especially "Use timer in seconds" and "Change timer/manually") while the ready slideshow (EXE) is beeing seen.
(When I prepare the slideshow, I don't know the situation in which the slideshow will be presented).
This change is only for active presentation, of course.

In this exe, there is no possibilities to have dialog box, so how?
