I look at the handbook which lists a slideshow config menu. I want to change the interval time.
I go to Settings, Configure Showfoto. All the configuration menus are there except slideshow. It should come after color management, but it's not there.

Never mind...I see it has been moved into the Slide show itself.
Setting the interval is awkward, would rather have a numeric time in seconds than the slider bar. At least make its ranger lower. Setting the slider any distance to the right yields an interval is minutes, if not hours.
Thanks for the lovely high resolution presentation of images
